hi all im trying to get my car ready for a remap and was wondering if my air filter was good enough to support around the 350 mark
has any one got one fitted with the same sort off power.its a apexi one like in the link. subaru 98 import maff sensor with apexi air filter on eBay (end time 16-Aug-09 22:07:15 BST)

any advise

 

It's the Apexi Power Intake filter (would've originally come as part of a kit including resonator delete pipe, oil/ISCV breather pipe attachments, MAF adaptor, gaskets, nut's and bolts, sundries, etc...)

JGM mapped a customer's 2.0L to 401bhp on one!

If you have it in your possession and you're able to measure the filter element's height, and the top and bottom diameters, then I can work out the CFM and, more usefully, its effective surface area (E.S.A) of it... and whether it'd be okay for your motor's:-

[cu in capacity x projected mapped absolute boost level (in bar) x peak power rpm point] / 20839 = engine's E.S.A.
