whaat the best for the 91 k5 with tbi?
We didn't test them on the OBS :neutral:, not sure what is on the market for you.
Jenna what about the NBS and NNBS trucks?
Hey Jenna Bear. I believe I've seen you on another club I've paroused through before...gm-trucks.com maybe. Glad to see you finally got over to the GMTC. Welcome. Good informational post, I'm actually currently in the market for a cold air intake.
Here are the results of our intake test-
From top to bottom on the horsepower curve on the graph is:
AEM no filter
Stock with KNN drop in filter
Stock with Fram airhog
i have a k&n on mine, and it has been there since i bought the truck, i was thinking about switching to a volant intake, about 2/3 of my daily drive to work is highway, but i do a lot of intown driving. i also like to play a lot. do you think this would be a good switch? i know you said its mostly personal preference, but i have heard more good about volant than i have k&n
Thanks for posting those dyno numbers. I think I'll stick with the stock air box and K&N filter. Maybe do the stock air box mod and add a smooth coupler.
Would you have some dyno numbers of the gains with air box and long tube headers? Before and after tuning also? (maybe you could post in a separate thread).
Here is an 05 Sierra with LTs, but not a stock air box:
Great informaton! Thank you for the hard work.
