Can't find the engine air filter thread!

Searching failed.

Anyway, 6x price difference.
Wix Fram K&N?
Will my engine notice a difference?

True confessions: I've been blowing mine out with the air gun and tapping it on the bench to keep it clean.

From tests I've seen, not Tundra specific, the better flowing filters can make small gains at WOT. The trade off is you are allowing finer particles into you engine. Also consider some MAFs don't like oiled filters. Doubt there is much to gain on a Tundra.

 

I’ve run across a couple of studies over the years and Wix has come out at or near the top in filtration and flow performance most frequently. I think Napa was up there too.

 

I personally suggest sticking with OEM part number 17801-0P100.

 

OEM or Wix. A high flow filter is not going to give you enough of a performance gain to offset the additional dirt they allow into the engine, and they cost more vs a stock replacement.

 

Since I just posted this in another thread just a quick reminder to not let the Toyota counter guy sell you the YZZ economy line for a savings of $2 or $3 bucks. Only buy 17801-0P100 if going with OEM.
