i'm new to this forum and i just purchased a 2004 g35 at. car came with aem cai, dc polished headers and full dc exhaust. considering plenum spacer upgrade but not sure what i need. do i have a revup or non-revup engine? any suggestions are greatly appreciated.

 

If I were you I would remove the cai and get the Stillen intake, that is if you don't plan on going with some type of FI in the near future. CAIs don't really add any hp on our cars and in some cases you could actually lose power. Since you have an 04 (non-revup motor I beleive), I would go with a plenum spacer. You might want to check out motordyne's website for more info.

 

U have a non-revup. Get the spacer, HFC's/TP's, lightweight pulleys, and a tune/reflash-that'd be a good start

 

thanks you guys...

so i have the "non-rev" is that good or bad? i will look at the spacers as my next upgrade.
