basically guys de-restricted the airbox and now i am waiting on my new sump getting delivered and will be doing another service while i replace this, basically just wondering whether to buy a k&n or pipercross panel filter instead of the standard 1,
best place to buy?? (ebay?)
any1 recommend another good brand??
any1 with an IS m44 put 1 in and noticed a difference??
am not doing this expecting a massive bhp gain etc but just even if it makes it run smoother or more responsive low down etc!!
