Never understand comments like that! Why would you throw it away? Just keep lowering the price until it goes?

 

It is a rather large item and space is currently at a premium following the arrival of a new member of the family. If I could hang on to it, I would. No one likes throwing money away...

Sponsored by Apexi? Those tests were quite futile I think and most of them were sponsored by one manufacturer or another. I've never heard of someone sustaining engine damage as a result of debris flying through the air filter, have you?

 

Can't see where it says Apexi sponsored the tests.

Logic would dictate that a filter with strong filtration qualities would naturally be more restrictive than one with less filtration qualities. Yet, in this test, Apexi appears to defy physics in that it is not only the best filter in terms of filtration capability, but also the least restrictive! :blink:

Perhaps so. However, it's most likely just a marketing stunt to boost poor sales vs the offering from HKS. I find it hard to appreciate these tests which simply do not appear to conform to scientific constants and completely fail to explain the methodology used; if you want more filtration, you need a more restrictive barrier, the more restrictive the barrier, the more power you would expect to lose...

It could be as simple as something like the Apexi makes the air go though more of

the filter, the speed it goes through at is still the same so no power loss but more filtration ?

 

It was a very simple test if i re call with some soot or similar a stopwatch and a vacuum cleaner, still rather

alarming what the difference was even if it wasn't really that scientific.

 

I can only go on my own car which had Apexi filters fitted to it, it was still on stock tubbies and had great leakdown compression tests at nearly 140,000 miles

If you look at the design and the materials used, the Apexi, Blitz and K&N all appear to use the same materials with almost identical thickness. Such a disparity in the test result is therefore something I cannot readily comprehend.

 

I'm sure the Apexi filter is a capable filter, I just don't see how it could be much better than the rest, with the exception of the HKS, as it uses a sponge type filter unlike the others.

 

I've personally used all of these filters over the past 11 years or so, including, admittedly, the HKS filter without any issues, ever.
