I've been looking at replacement air filters, and came across the K&N drop-in replacements, but haven't heard much good about them. So I've been browsing these hallowed forums (or should that be fouriis, or foureyes ?) and came across a thread mentioning Streameline drop-in replacement air filters - meant to be the bees-knees

The link on that thread doesn't work now (something to do with helene) so, please, can anyone enlighten me as to where to get a Streameline filter ?

Or are there any other suggestions ?

:)

First of all, ask yourself what you want out of an aftermarket air filter. Is it noise? Is it power? Is it better filtration?

BMC, RamAir, K&N, Streamline, Pipercross, etc. will all offer/claim similar performance increases over an OEM filter, however none of them will guarantee you any power increase (despite 'inferring' this in their marketing material) as there's nothing wrong with the OEM filter.

If it's a dry filter then check how big the collection surface area is compared to the genuine one as some of these performance filters are less restrictive simply due to the fact that they've got less folds/pleats/surface area than an OEM one.

If it's an oiled filter, then it's only as good as the maintenance regime the user follows. Too much oil and it hampers performance. Too little oil and it hampers it's filtration effectiveness.

If you want to spend up to 10 times the amount for a 'performance' filter then do so, but don't buy one expecting anything other than a tiny increase in noise/power.
