That's so sweet!!!

I wanted to put dual quads on my 428 powered 69 GrandPrix, but l couldn’t afford the tunnel ram and dual 390s.

Seeing dual carbs on a tunnel ram always brings me back to those days .

Thanks for sharing

The search function only showed discussions about the CAI vs stock filters... Has anyone had any positive results with the drop in vs stock (besides any performance gains from having a lighter wallet)? I'm sure i don't want to spend the money on a CAI.

I have a 2014 TRD Sport with 52,xxx miles. I probably averaging 13-14 mpg with a stock truck except for 265/70/17 BFG AT's.i'd love better mpg's (who doesn't), but i don't see my driving style on the highway changing much any time soon.

Complete waste of money and time,factory filter is better,so why would you change it.

I run drop in K&N's in all my cars; 50 year old dual-carbureted Euro sports car, few year old Euro performance FI coupe and the Tacoma. I don't do it for performance; I just hate to toss out air filters when I can clean and reuse.

I use the dry washable filter by aFe. It is great, once a year I rinse it, nothing else to do.

Oh yea that reminds me, I ripped that charcoal secondary filter out too. Seemed like an unnecessary restriction, there for emissions or something.

All this discussion on K&N Filters got me cleaning spare air cleaner early !!!! , it's nice and clean and will let it dry for the next few days before oiling it
