bellicose 9 Report post Posted July 16, 2009 Hey all, Just wondering if i can delete the panel air filter and replace with something else? The current filter is ahead of the AFM, already sorted exhaust and just want to free up the intake flow abit. cheeRS Quote Share this post Link to post Share on other sites
bravo 35 Report post Posted July 16, 2009 The BMW AFM's are fairly well designed (based on anecdotal evidence on dyno runs with and without an AFM). Aftermarket (eg K&N) panel filters free things up somewhat. The gains realised with a pod filter are usually negated by extra heat in the intake charge (often they give worse performance than a stock system). A properly designed cold air intake with pod filter can give small gains. Some motors respond to changes in the throttle body and intake manifold. Many of the claims are unjustified, or subjective, and it depends on your motor. There is some evidence to suggest that there is room for improvement here, but it's a bit of try it and see. Best option on a budget bang for buck is a good quality aftermarket panel filter. Quote Share this post Link to post Share on other sites
