are they the exact same air filter? if so what is the product code i need?
how much are they a peice in uk? as it takes two right?

 

The Crossfires use 2 of these filters.
The part # is 33-2290
They are available from the K&N website here
It appears from the info on the K&N website when looking up filters for the SLK that ours are different.

Hope this helps.

 

I replaced the air filters on my roadster with K&N. The original air filters are marked Mercedes Benz with the number A-112-094-03-04 (Mann air filter). There are also two smaller codes: C2861 and 041103 to the right.

 

If you want KN filters I can ship them to the UK for a lot cheaper then most.

We sent a set over about a month ago and it came to $85.00 with shipping.

Let me know if you want them.

I can do even better if you don't mind a set that's not in the boxes, basically used for 3-4 dyno runs.
