Fit, finish and quality of the Injen Power-Flow CAI was excellent. Clear, concise instructions right out of the box and after installing it, I did notice a feeling of performance increase. It won't make you think you just gained 20 hp, but it will tell you that something extra is there. Well worth the money just for the "Performance Sound" and - as always - AutoAnything had a better price than anyone else out there.
Injen CAI Install Duramax diesel
Quality product, well made, not to hard of an installation, just made it a little hard on myself with the installation, puting way to much thought into what i had to do, the tools i needed, etc.., i made it a 2 hour install, instead of 45 min. to 1 hour The Injen CAI looks awesome under the hood compared to the smaller stock chevy cai that was removed, smoother cleaner larger air box, large air filter, engine sounds completely diiferent than before, YOU WANT SOME, COME GET SOME!!!
