Just popped this in my Dad's Alfa Romeo Brera 2.4 JTDM. The difference was very noticeable when I took it out for a test drive. The engine was much looser and responsive. Only giving 4 stars as its just been put in but I'm sure it's worthy of 5. Gave me that extra little push back into the seat : )

I ordered the above air filter last week, after not being able to locate one in New Zealand.  Your service has been fantastic, it has taken about 7 days to be delivered.

I received it this morning and installed it in my Alfa Romeo 156,  the car responds instantly and accelerates so much better.  I had put one of your filters in an Alfa I owned a few years ago, but had forgotten how good they are.  Such a difference in performance.
