Can i install a Cold air int inake Ford Ranger?

Answer 1

You can install an aftermarket unit but technically most draw HOT air from UNDER the hood in the engine compartment and ARE NOT a true cold air intake. Modify the factory airbox if you like and allow it to draw COLD air from behind the front grill (as it is designed). Your truck will perform just as well and if you do the work yourself, you save money. Enlarging the intake tube to 3" PVC works rather well as a cold air intake (behind the headlight on some model years). Use a 3" PVC threaded coupling on the outside of the filter box and the 3" flanged threaded adapter on the inside to hold it. If after cutting there are small gaps, just seal um up with silicone sealer or what have you. This is a sizable increase from the factory intake tube. You'll just need to make a larger hole in the front or side of the filter box and can even reinstall the water-guard if you wish when you're done. Some owners have even drilled holes thru the bottom of the box in thru the top of the fender into the fender well and located PVC piping there to assure a true COLD air intake. When turned down and towards the back of the truck it is less prone to suck in any water during a rain plus it is beside the tire in the fender well....not behind or in front of it. You can get a K&H factory replacement filter if you just are looking for a power increase or add it to an air box modification. About $8 for PVC parts.
