I have for sale a Japan Made Gruppe M True Carbon air intake with K&N performance air filter + K&N recharger kit.
I bought this intake for my Mercedes, but unfortunately it doesn’t work as well as I expected, because it is specifically made for BMW E39). I am now looking to sell it.
Performance Improvements? This filter increases the engine’s ability to breathe, and thus it’s power output. This was definitely for me in the higher RPMs. The sound of the acceleration was also improved with this filter.
Compatibility? This Gruppe M model is 02 01 11 and is specifically made for BMW E39 6-cylinder models: 520i, 523i, 525i, 528i (The 530i and 540i V8 both have bigger mass air flow sensors). On the 3-series (E36, E46) it does not fit because the carbon housing is too large to fit under the hood.
Condition? This intake is used, but the carbon condition is simply perfect, there are no scratches, etc. The K&N filter is also in good condition.
Price? $150USD plus shipping. I am located in Republic of Georgia in Tbilisi. If anyone has interest, please contact: Daviddolidze500@yahoo.com.
I removed this intake from an E39 523i M-sport.
Here are the original pictures:
Before i removed it looked like this on E39 523i:
