I'm thinking of a plenum spacer but don't know which to go with, 5/16 or 1/2. Also which CAI would be the best choice between Injen and K&N?

 

injen is da **** even tho i dont have it. its still dabomb

 

Don't waste your time with the Injen. The best "gains" will be felt with an OEM Z-tube used in conjunction with either a K&N OEM sized air filter or a popcharger.

 

^^^^ +1 !

 

get md 5/16 spacer and stillen CAI/Z-Tube combo

 

Thanks for the replys. Will any of these mods. void factory warrenties?

 

Any modification that exceeds stock specifications can void your warranty. You got some laws to back yourself up though. They can't just void your warranty because they think your mod is the cause of a problem, when in reality, it is not.

 

i have the new injen 1993 with MD 5/16 and iso thermal and its just wonderful a bit of high end gains and made my G go vroooom a bit louder

 

any mods will void factory warranty only if you blow the engine or there is a problem caused by one of the mods.

this is what i tell my customers b/c i work at a mod friendly dealership. you don't know the number of cars that come in modded and we work on them
