Air Filters

[Grandavi]

well.. I've been happy with my K&N, but generally, I dont see the point of putting one on my 90 Supra or my 2006 Sienna (both of which I was going to do, but now wont)

Another big thing to take into account beside power gain is restriction.

Keep in mind I'd be using the stock airbox if i could have with my IC pipes, but I run an Apex'i

2X Engine Protection..... 2X!!!!!!!!!!!!! Fram claims 100 HP gains on this filter. It was tested against walmart's super tech, auto zone's stp and blew them out. Super tech was very poor, Stp was good, Fram was excellent........

:rofl: I about died

I will be making a custom airbox guys, for whatever cone filter I use on the 4" turbo inlet

Apexi all the way. Blitz a no no. Take a look

oh, damn just saw the test results

I, for one, love hearing the intake noises. In addition, a car with more than 200 "kw" (or whatever pretend unicorn magic you aussies want to quantify it with) will likely have a bigger difference at higher power levels

Spiral wound hose is a known restriction, they added a metre of it and wondered why there was little increase...

Guess they've based the show on MythBusters so flawed science and results is expected..

That's exactly what I was thinking IJ... and yeah I don't much care for mythbusters. They may as well all be wearing "dunce" hats.

Actually its called mighty car mods. They have an episode of swapping a 1jz into a cressida. I like watching their shows.

Gotta love the accurate representation of the demographic...

After many years of K&N, I now have an Amsoil dry filter... Went off of the filter comparisons available on the interwebs. Lots of it showing K&N performance being much lower than you'd think.

Keep in mind that in order to have an increase in either flow or HP whatever filter it is, is allowing larger particulates to pass through its media. The larger the particulate boils down to more wear on metal parts. In the case of K&N or any other filter for that matter, it's very easy to see this by placing a piece of white gauze material on the inside just like Bob the Oil Guy Did in his tests. I'm sticking to Wix, and that’s my story.

Like already said, that only applies if the filters have the same surface area. Larger the filter, the more flow you cna have with the same filtration.

yep... this is pretty basic and straightforward.... the more surface area you have, the more you can increase filtration quality while keeping the same if not better airflow than the other guys.
