my review on a stock airbox vs pod

[JimX]

Excellent airflow if you ask me...

I don't think that's a very good test. Your engine sucks in probably 10000 times as much air than is required to lift a ping pong ball. Also, the test doesn't mean anything unless you have other filters to compare it with in the same environment. Who's to say that a standard paper filter isn't going to flow just as well at those low air speeds?

Whatever the case, it would be interesting to see how filters other than the K&N one stack up in the ping pong ball test.

True the amount of air flowing etc isn't anywhere near the same but I would have thought that by putting an airfilter over the open hole that it would restrict some of the air.

The guy that served me said he tried a K&N panel filter in his VLT and didnt notice anything over the stock filter but noticed an immediate difference when he put the Redline filter in place. Most likely just sale/mechanical dribble again like all the other shops.

I had a Redline filter in my car when I got it. When I replaced it soon after with the Apex pod I had a look at the Redline one and saw large visible holes in the mesh. Maybe about the size of a grain of sand? I'm just glad that my engine or turbo didn't suffer, but that'd be because the previous owner didn't go driving through any sand storms.
