These are simple and inexpensive. Fit nicely into a 50mm trumpet.
And a true restriction for airflow...
Hi,Has anyone ever tried to create some sort of custom made air filter in the air openings of the rear clip?
Yep- they're screwed!Paranoia ! Real men done use filters , or condoms , nor do race cars
The type of piston rings makes a difference. Without an air filter, chrome rings last longer but take longer to get seated in the bore when new. Softer , moly-filled rings seat quicker but, as they are softer, wear quickly in the presence of airborn dust & grit. Dirt track cars almost always use chrome rings.Air filter or no air filter? For utmost performance and for a short time: no filters. "short" depends on ambient conditions and luck. For longevity and slightly lower performance: filters. ``slightly" depends on the type of filtration. I clean my filters (K&N, ITG) typically once a year - and usually I am glad I did use them. I was told by a guy who did prolonged test bed runs (on E-Type Jaguar engines) that power degradation due to lack of filtration can be observed as early as after one hour.

Not quite, Hot Rod Magazine did a test on air filtering.Yeah JP, just like any kind of air filtration.

Paper elements are best, only robs a few bhp.
Second comes K&N
Foam resticts a lot and mesh even more.
