Air filters.

[Sud 145]

Can any of you guys vouch for gains from fitting so called "Performance" air filters?

I would say you couldn't tell the difference in road use. In fact, in some cases the all-round performance could suffer, my K&Ns don't have any provision for thermostatic inlet temperature control, for example. But they do make a nice noise

another issue that I note the TS engines in particular suffer with is oil contamination from the filter oil getting onto the air flow meter and ruining it...

Was considering for the Sud following her engine rebuild but the cost for virtually no gain, don't think it's worth it. Thanks for replies.
