I want to unmount the OE intercooler and clean it ,inside and outsite.

Is necesary to unmount the front bumper for that or just the wheel arch is enogh?

I was thinking to clean the inside with some petrol....

Any ideas?

The bumper needs to come off but it's quite easy. The black strip pops out then there's a couple of 10mm bolts easch side, and about 15 torx screws around the wheel arches and underneath.

thanks both of you,the biggest worry is not unmounting the bumper ,the realignment is.

I think I remounted mine with the help of a friend, either that or I had it resting on some axle stands while I bolted it back on

If doing it on your own make sure to have a dust sheet down. I have taken bumpers off before, easy done. But when you try and put the them back on and accidentally drop it on the tarmac is a right kick in the teeth
