There is no black and white answer to this one. If you changed the air filter, and your brakes started to play up, there probably wouldn't be a problem. But if you changed the air filter and the engine management light came on, whether it was the filters fault or not, you are leaving yourself wide open for a bill to correct whatever is wrong.

Perhaps I might wait for the 5 years warranty to expire.

Hi guys,

looks like BMC filter for GPA has some problems now.

The problem is that due to the high temperature below the hood, the filter become deformed like this:





by now, we DO NOT KNOW if this is really a problem. We contacted BMC staff to have a reply about this. They are investigating the issue, i will let you know as soon as I will have any news (in a few days, I think).

DON'T PANIC FOR THIS: nobody had engine failures or broken parts due to this issue. BMC does not know if this really is a problem. The odd fact is the the K&N filter does not get deformed, and not every BMC get deformed (10% is good, 90% gets deformed). However, BMC is a good company and it's making tests to give as an answer as soon as possible. Many EsseEsse in Italy are equipped with BMC filter, and no one had problem.

I'll keep you updated from Italy. I have a brand new BMC filter, and I'm waiting for equipping it.

Bye,

Irvin

I noticed that the engine bay does get exceedingly hot.
