Evotech rad/oil cooler guards

[mahseve33]

Looking at posts for rad and oil cooler guards, Evotech seem popular, look good with better fittings, IMO.
Somewhere I remember seeing a comment about inhibiting cooling effect and BMW not covering warranty if fitted.
Anybody experienced this or challenged the warranty aspect?

Hi
No problem. Have them fitted and have been running during the last few weeks heat without problems. My local dealership recommended them but would not fit them.

The dealer fitted mine, supplied by me, before I collected the bike
Have had no overheating issues in the Irish 'summer'
But the powder coating has worn off where the sh1te from the front wheel hits it
