What's the best to fit! Want one that doesn't need oiling! Want to make the mass air flow sensor last!
yes the are, and personally think it does not makes a noticeable difference to risk damaging the MAF with the oil of it
I have the Pipercross filter in my R26 and, tbh, I wouldn't recommend it. After only about 5 months, the foam has started to come away from the mesh backing in the middle of the filter. It still works perfectly fine but I find it odd that that has happened after a relatively short period of time.
