DEPENDS ON WHAT TYPE OF INTAKE AND CARB. YOU'RE BEST BET IS TO GO TO EDLEBROCK.COM, ENTER THE CARBS MODEL NUMBER, AND GET A SPEC SHEET THAT THEY PROVIDE.
a k&n filter and the best improvement you can make would be to upgrade the intake manifold to an edelbrock performer tbi and a turbo cities 620 cfm throttle body
depends on the size of your cam, the edelbrock rpm air gap is good to 6500 rpm and is an all around good intake for street use with a two plane plenum. the edelbrock non rpm is better for smaller cam, good to 5800rpm and sits lower than the air gap for better hood clearance.
The process is time consuming... The intake manifold has to be taken off and the gaskets replaced due to the spark plugs being under the manifold. It would be best to take it to your dealer.
A performance exhause, intake manifold, corld air intake, sparkplugs, spark plug wires, throttle body and headers by any brand name will get your honda roaring.
I've noticed better MPG. Look for an air intake with a heat shield, for best results.
Best place is in one of the cylinder heads, by the spark plugs. Or, the intake manifold, near the thermostat housing.
Sanderson block hugger headers. Not cheap but good quality part. 99% percent chance will work fine. I have a 1970, 429 with a Volare front suspension and these headers were the only ones other than the stock manifolds that would work. Stick with an edelbrock dual plane and vacuum secondary carb for best street performance. Hope this helps.
I would use split fire
the best way to improve performace is by buying performace spark plugs, spark plug wires and adding a air intake on your vehicle. As well if you dont believe it or not buying that Quaker State Horsepower engine oil will help out a lot.
get a universal fuel pump from any auto parts store you want to run between 4-7 pounds of pressure
I've had good luck with the Edelbrock 1406 right out of the box.
