Air Filters and Intake Manifolds
Air filters are devices that remove solid particles such as dust, mold, and bacteria from the air. Used in building ventilation systems and engines, they contain an intake manifold that is primarily tasked to optimize the system/engine’s performance and efficiency.

If the intake manifold gasket is replaced should not the radiator be flushed along with repair cost?
YEs it should!! the tech is trained to accomplish all that > when a car comes in they cannot let the car leave if there is still something wrong like the radiator not being flushed after changing the manifold gasket, your tech was probably hoping that you would pay the extra cost.
What vehicle did the manifold with casting number 1731703-2 come off of?
I believe that's a 392 Chrysler hemi manifold, 1958.
Do you put motor oil on intake manifold and oil pan gaskets or carb gasket?
No you do not, you would put oil on a oil filter gasket if it is a spin on type, this stops the rubber from binding and helps it seal.
Your 96 cr 125 keeps blowing head gaskets?
When installing the cr 125 head gaskets, make sure to check the surfaces for any old gasket materials or scratches. Check the head to make sure that it isn't warped. Make sure that the cylinder pressure isn't too high. Tighten the head bolts in the proper sequence and at the proper torque, and the gasket should stop blowing.
What are the bolt torque values for the exhaust manifold to Y pipe on a 95 Astro Van 4.3L?
It should be about 45 ftlb
Does a 1999 Toyota Tacoma 2.7L have a cabin air filter and where is it?
no cabin filter in the 99 tacoma. only 2002 and later.
How do you find and replace an exhaust gas manifold sensor on a 2001 Ford Taurus?
Lots of good coverage in the "401" "Related Question" below...
Answer
I think you're referring to an exhaust gas oxygen sensor. If you have a V-6, there are at least 3 of them. You will find 1 sensor in each of the exhaust pipe coming down from each bank. Those are called upstream sensors. There's also one after the catalytic converter. That's called a post cat sensor and they rarely go out. If you have dual exhaust, you will have two post cat sensors.

What does the manifold pressure sensor do?
The Manifold Pressure Sensor (also known as the Manifold Absolute Pressure Sensor or the Manifold Differential Sensor) is a device that is used to calibrate the fuel delivery on most modern ECU Controlled (computerized) engines.
Used predominantly after the institution of the OBD-II (On-Board Diagnostics), it is used to calculate the difference between manifold pressure (measured in inches of mercury) and ambient or atmospheric pressure. The computer uses this sensor to determine, based on the differential between the two, the conditions present requiring the fuel delivery to be adjusted.
At higher altitudes, the ambient pressure is lower, reducing the value when comparing the two readings. At lower altitudes, the atmospheric pressure is higher, generating a larger number. The larger the number, the less fuel is delivered, as decreased atmospheric pressure indicates (under normal conditions) a decrease in the density of the air and thereby a decrease in available oxygen, the second component required for efficient combustion.
Additionally, when the throttle plate is opened, the value generated by the Manifold Pressure Sensor (usually called the MAP) is reduced as the pressures equalize. This tells the computer that the operator is attempting to accelerate, adjusting timing, injector pulse width and other sub-systems to assure proper and efficient response.
How do you change cabin filter 2004 Toyota Sienna?
Very easy. Open passenger glove box (lower bin). Push in on both slides of the glove box near the rear of the glove box, this will let the two rubber pieces disengage and the glove box will come down even farther. On the left hand side you will see an apo. 3" tall by 10" long possibly white cover with two little prongs on each side. This is the filter tray. Grab the two prongs and pull outward, the entire tray will come out and you will see the filter. Take it out, replace it (just drops in) and put back in the slot. Close the glove box like normal and you are set! Takes 2 min to do. Show replace your cabin filter every 12,000-15,000 miles or more if you live in the desert. Shop around online and you will save some $$ if you buy filters online compared to the auto parts store.
What does a performance air filter do in a car?
Your car's engine is essentially a giant air pump, combusting a mixture of fuel and air with a carefully timed spark. The more air the engine has available, the more horsepower it can make. An engine that breathes more easily will also show improvements in throttle response. Throttle response is measured by the amount of delay or hesitation that your car exhibits between when you press down on the gas pedal and when the engine responds by delivering power. Improvements in throttle response give you more "pep" in your car's acceleration.
Why does a car backfire through the intake?
timing is off. this is correct, but to find out WHY it is all of a sudden backfiring you gotta start from the beginning.... I am posting this because in my painstaking search for a solution to my car troubles, all i found were half answered questions or people not posting after a repair was made so we can all know what worked and what didn't.. HERE IS WHAT I FOUND..... I've had a problem with my 1992 Lumina 3.1 ever since around Thanksgiving when the temp outside dropped below 50 degrees. before that, the car would start with absolutely no problems. since then, when i crank the motor, the engine feels like it's going to catch but doesn't- just sputters out and backfires through the intake.. after reading so many threads and "solutions" on the 'net...i checked a few things... found that my fuel pressure regulator was leaking fuel through the vacuum port.. also read that a leaky regulator would cause a no start like mine especially in cold weather because without the proper amount of fuel and spark, you wont get the car running. OK!! SO!! after spending 650 dollars to replace the fuel pressure regulator (on the older model Luminas its located under the intake plenum, so the whole thing needs to be removed), AND a new starter since I overcranked mine 1 too many times, the car started right up at the shop.. NEXT DAY THOUGH, cold as hell morning, no start and STILL backfiring through intake.. the mechanic at the shop insisted he take apart my intake again to check voltage on all of my injectors, but thankfully i hadn't enough cash after the 650 wiped me out... REMEMBER...my car ONLY BACKFIRED upon ignition... after i got the motor running, my car ran like a dream.. so in reading hundreds of other posts i determined that it was either gonna be my ignition control module or crank sensor, or a combo of both.. i got crafty this morning and went out to the driveway with an extension cord and my sister's hair dryer... i put the hair dryer to the ICM and the coils that mount to it for 5-10 mins.. low and behold, my car started right up without hesitation or backfire. i know this post has been long, but like i said, I'm only doing it so that maybe the next poor guy having similar problems will come across it and get closure and hopefully a solution. my icm needs replacing soon as i get paid
What is the torque spec for the water pump mounting bolts on a 2000 subaru legacy?
The torque should be around 11 ft-pounds
Will a leaking lower intake manifold gasket ruin a engine?
It is possible if the leak is a "internal leak" - where the coolant is leaking inside the motor and mixing with the oil it will ruin the motor. This will eventually cause bearing failure. If it is an external leak - as long as you keep the coolant full and watch your temp gauge, you can get by for a while. Keep in mind - the leak will only get worse as time goes on.
Looking for a turbo kit for a 1999 jetta 2.0?
You can not get a turbo kit but there is a nuespeed Supercharger kit for the 2.0 it gives you 50% more horsepower and 55% more torque.
How do you replace an air filter in a 1999 dodge grand caravan?
When you open the hood, there is a plastic box to the right side that says "remove to replace air filter". Do not try to pop the top off of this box as i did, instead remove the two screws holding it to the body of the vehicle. The box containing the air filter is located beneath the box you just removed. There are two clips holding the cover on the box, undo these and you will see the filter sitting vertically in the box, replace it, put the cover clips back in place and replace the plastic box that was removed first.
Where is the air filter box on a 2000 Toyota Celica?
I just checked mine today. Its in the very front on the drivers side under a rectangular cover that has a couple latches you have to figure out. Not the one that says "Do not remove". In front of that one. Hopefully I have helped!
What is a 346250 intake manifold?
It is an intake off of a late sixtys small mblock chevy. 350cid or 305 cid
Torque specifications for 5.3 Liter Chevy upper plenum?
First check the plenum for warping by using a straight edge across the intake ports and a feeler. If warpage exceeds .100, replace the plenum.
If not warped beyond specification, replace gaskets and torque in two steps, 1st step 44 inch pounds, 2nd step 89 inch pounds using the pattern shown:
10 4 1 5 8
FRT
7 6 2 3 9
In case this does not format correctly try this:
From front of engine, start with 3rd bolt on left, then go to 3rd bolt on right, next 4th bolt on right, next 2nd bolt on left, next 4th bolt on left, then 2nd bolt on right, then 1st bolt on right, then 5th bolt on left, then 5th bolt on right and finally, 1st bolt on left.
Fairly easy. Unbolt the stock air filter and intake and bolt on the new on. This really is a "bolt on" application.
What does a manifold do on a car?
There are basically 2 manifolds. The intake manifold routes air to the engine and also fuel on a vehicle with carburetor or throttle body fuel injection. The exhaust manifold routes exhaust gases out of the engine to the converter and then to the tail pipe.
How do you change the air filter for a Goodman?
Locate the filter and remove it, then reverse the procedure, being sure the arrow indicating direction of airflow is pointing in the right direction.
