Does anyone know the tubing size of an aftermarket intake?

RedBaseBolt

Usually 3 inch to the throttle body.

I guess its 3 inch but it maybe depend on each brand

NSChiCobalt

should generally be the same, just looking to find out because im doing a custom intake....

Nuclear

i believe the injen is 3 inch

IonNinja

anything between 2.5" and 3" and you should be fine. just make sure you have a way to include the maf in your custom intake.

Actually most use 2 1/2" alluminum tubing...some companies go with a 3".

The injen flares to maybe 3" at the filter but the majority of the piping is less than 3". I have a gen 1 injen pipe at home I will measure it later today.

JBP and Fujita (I believe) are the only true 3" intakes that I know of.

I didnt realize this is in the 2.2L forum... oops sorry

For those who care the 2.0 Injen is 2.75" where the pipe meets the filter, then it reduces to what I'm assuming is 2.5"
