Good job on the test. Its a shame Perrin didn't hook you up.....

 

I cannot believe Perrin wouldn't give you a free filter! Do you have any Idea how much revenue they're going to see based off this test alone. Tsst Tsst Perrin even though I will probably end up buying one too! haha

 

i am glad I have a brand new buschur old style filter

 

I have sent a link to this thread to Buschur, Oil Doc, Perrin, Vibrant, and K&N so hopefully they'll weigh in on the results.

 

Not much to weigh in on The testing looks fine to me and makes sense our old style filter made the most power as the car was tuned on it. I'd venture to guess the results could be brought closer to original filter with some custom tuning.

Thank you for the time you all put into the testing. I am more than satisfied with the results.

 

thanks for doing this test. i was stuck on apexi (have ran them on other cars) but after seeing these results, i might have to reconsider. its crazy how some are up on HP compared to others and vice versa with some on TQ. thanks again!

 

Chris,

Thanks for the tests and the mention.

I had little doubt that the Perrin would flow well being the type of foam filter it is. I am very familiar with that filter as it is the same as the old style AMSOIL Filters that we let go of a few years ago in favor of the equal flowing but better filtering Media we now have.

As shown in these tests, The top filters are pretty equal as far as flow, so 1 or 2 HP is not worth the dirt ingestion to me. I s**t canned the K&N after my oil analysis showed it didn't filter very well.

The same filter used in these tests, AMSOIL EAAU-4560 coincidently is $45.60 Plus Tax ordered through me directly. Normal Retail is $51.35 plus freight for $58.45 plus tax.

This is a 4.5" inlet X 6" long filter.. Other sizes are available, prices vary.

We also carry the INJEN intake systems which after Injens tests, now use the AMSOIL EAAU Filters

Good stuff, thanks for the info. I don't see anything that is gonna make me run out and replace my apexi, but if I had to go with a replacement I'd do the amsoil.

 

+1

 

I'd like to see the dyno charts for each to see the variances instead of just peak numbers. It is good to see what the perrin put down (since i just got their intake) but i am surprised to see the torque numbers from the apexi.

 

Thank you for this informative test

 

nice works.

good on MAP for the dyno time

 

Nice test, well done to S2k & Scheides for getting this test done. Big wraps for MAP donating the dyno time as we all know that can get costly.....buy the filters from these lads it's only fair.

Cheers Steve

 

very interesting results!

 

what are you going to do with the filters? PM me if you want to sell the AMSoil one.
