    Stock Cold air intake performance upgrades

    I already added dual exhaust to my ‘86 K5 with LE9 305. Stock numbers are 160hp @ 4k rpm and 235tq @ 2k rpm. I removed the very restrictive metal mesh flame arrestor? Which I immediately felt some hp improvement. I thought about going to the standard open element air cleaner but I like that...

    Front center seat, center console upgrade, 3rd seat, 6th seat, jump seat

    This bolted right into my k5 Blazer. I can now seat 6, more importantly I have a useable center console with lots of storage and cup holders front and rear. 2007.5 - 2013 Silverado, sierra, Tahoe, suburban, Yukon GMT900 generation. 2014 - 2019 K2XX are very similar and would work as well.
