so im thiiiiiiis close to getting either the injen sri or injen cai. ive been looking through the threads on pros and cons of each, but not sure how they stack against each other. im more interested in a nice sound vs hp gains. what do yall think?

 

i had the fujita then JWT then Injen CAI. the Injen CAI is my favorite sounding of the bunch. plus it actually has a bit of grunt in the upper rpms

 

i had aem dual 0n 07 z jwt on g37 now injen sri. I vote injen sr because of the ease of installation, and dyno graphs shown as well as sound and performance it gave. very simple upgrade and very well designed imo. injen cai and stillen are to much of a hedache to install and did not want to remove washer fluid or take off bumper... injen SRI gets my vote. and non oiled filters

 

+100!!! These are the EXACT reasons I bought my Injen SRIs that are getting delivered tomorrow!! Plus the filters are Amsoil Ea Nanofiber filters which are about as good as non-oiled filters get.

 

The Injen CAI, from what I've heard is a PITA to install. The SRI very easy. CAI has more HP increase than SRI as stated by dyno posts. But then again, dyno claims are so subjective nowadays. Our cars also react differently to these mods.

I went with SRI for the ease of installation, looks and sounds. I like seeing those blue dual intakes when I pop my hood up.

My opinion is, if you're expecting hp performance gains, then you may want to go CAI, if not then stick to SRI.

 

I only have experience with the injen CAI, but honestly man you can't go wrong with either. If you want to do it yourself, but afraid to take off your bumper then get the SRI. I have no problem with a little more difficult installation, so CAI was for me.

 

What are the differences in HP increase between the two?
