Weber 45 air filter replacement

Post by scottie84 » Tue Feb 07, 2017 5:43 pm

Hey guys and gals, can anyone point me in the right direction to get a couple of new air filters for my Weber 45 Sidies on the 4AGE? It appears I have some oddball rectangular filters on there at the moment as all I have been able to find that come close are oval type. Dims 166 x 110 x 43. Or should I scrap the current set up for an improved design?

Have a look at Uni Filters

I had some sock filters and then went to a Uni filter - much better
Some of the models have a blank base plate that you can cut to suit

You would notice a performance improvement if you could run some short trumpets inside the filter... dyno testing on a motor of mine really smoothed out the power curve.

I used a pipercross foam filter on a single back plate... Palmside has them in NZ, cheaper from demon tweeks.

Thanks heaps guys, I've been doing a bit of digging and looking in to trumpets so I think I'll go that way.

K & Ns are pretty similar and were standard fitment by Caterham.
