I have just fitted a set of BMC filters to the C43. I have fitted them to my RENNtech carbon airbox. They will also fit a standard C43 too.

BMC make filters for most F1 engines, world toring cars ETC so I thought I would give them a try. The advantage is that they are lifetime filters that can be cleaned. I will never have to buy another set. There is supposed to be a performance gain but it is very difficult to measure.

I have taken pics of every step.

Standard filters in place


Airbox front removed


Intake pipes removed.


Air box upside down on bench


Removed retaining screws.


Split airbox in two.


Old AMG filters


BMC filters fitted


Perfect fitment.


Fitted.

During road test there is no extra engine noise either.

Fitment was very impressive. They fit better than any other aftermarket filter that I have seen before.

Overall impressed. They were £89.

Olly, they look very much like the K&Ns, but i add BMC`s are cheaper in price

It HAS to be done. CF air, and de-cat and BMC filters = 400+ BHP.

So, can someone explain what is the difference between the standard AMG air box and the Renntech one? Looking at the photos I don't see any difference apart perhaps at the back (thicker perhaps?) where the body fits over the MAF

I know, I do want the Renntech box but not too keen on their remap.

A De-cat and a West-Tuning remap is my next two modds, which should give me 400+bhp & if I get the Renntech box at a reasonable price then it's a bonus but only you can sort that out for me.. :)

I dunno if it was in addition to the other mods too :thumb:


Renntech say 15-20bhp from this airbox with their remap, but it's allot of money for that much power, a decent remap could get you more power.

They normally won't sell it alone, they provide it with a remap only.

Olly would know more.

The difference is mainly heat soak and the shape of the itake is very much different.

Love that Airbox :D how much is one Olly ?

£1100+vat including the re-map as a package.

Looks nice!-i presume they have to be "cleaned" after a certain mileage:thumb:

I am going to clean them every 10k.
