A clean filter does not do its job well. Just some food for thought.

hehehe, after using aftermarket filters for the past 6 years, i finally gave up the habit and switched to stock. La lang. True, there are performance gains but i must be getting old and dont want the hassle of cleaning the damn thing.

I used a Finer Filter brand drop-in. A lot harder to clean than K&Ns.

K&N user since december 07 .. IMO mas matipid sa FC both gas and diesel ..
nagka fruity engine sound yung altis ko wich is much greater to hear ..
but may malakas na hissing noise sa trooper (diesel) but both of them increased in acceleration and much smoother i-drive ..
here are some pics ..
sa SPEEDLAB ko nabili .. trooper is 5500Php and for altis is 7000Php

Chrome yung side ng K&N ko with engraved K&N decal

1.8 1zz-fe mas malakas acceleration and much better FC ..

ask ko lang sir memphis malakas din ba hissing sound sa dmax mo? hindi kaya cause ito ng turbocharger? much greater ammount and pressure ng air ang hinihigop papuntang engine ..?

just would like to share my experiment a month ago or so. I am also curious to use a drop-in k&n's too. considering good result of diesels on dyno tests.

I removed our ordinary air-filter and have a jack rabbit acceleration test for our Pajero m/t 2.5TDic and Townace a/t 2.2TDic.

as far as responsive is concerened, didn't feel any gains at all. I was hoping removing it will help remove our van's intercooler turbo lag but it didn't. turbo pressure readings didn't improve.

I think significant improvement is noticable when you drag race style driving it. since I did not attempt to try it on my test.

and I don't think these filters will be noticable on a conservative driving and low and steady rpm driving style. I bet this filters will not help a n/a diesel engine.

the turbo-washer mod proves to be way more effective.

but, I would still like to try this filter myself and test it on everyday roads.
