I just received my second performance OFV, I wanted a spare.

I installed the first one about a year ago and have been very happy
with the performance improvements.

Prior to installing the performance OFV I had replaced the vehicles
original OFV with a new ME/BE OFV. It is a maintenance item.

There was a noticeable improvement in drivability as
compared to the old one.

The car (85 SD) no longer felt like it was
running out of fuel at higher RPM's.

However, the performance OFV is a substantial improvement over stock.
Acceleration and drivability are greatly improved.
The car no longer behaves like an old diesel.

Highly recommended.
