Ok guys I got the stillen intake and z tube...

For the plenum I can get a first generation crawford plenum (ugly with welding marks) or get a motordyne 1/2 spacer for the same price. This is my next mod. What do you guys recommend?

I plan on going test pipe or high flow cats next...FI is in the future... thanks for your input.

 

Ditch both, get the M/D 5/16 spacer.

Alot of people say they are going F/I in the future, if this is honestly true in your case, don't bother and just save up.

 

motordyne all day long
