I recently purchased the lipp intake adaptor and the spark plug valley cover mirror'd.
The adaptor had a lipp on it that allowed for a very good fit with the AEM 3" dryflow adaptor. the MA-70 stamp on it adds a nice touch. It was a very solid piece and looked very nice.
The spark plug valley cover looked very nice mirror'd however its very very difficult to keep smudges off it. The surface also seems to scratch very easily if i were to buy it again i would probably just go with the brushed look. Very solid piece of metal and was easily installed. I used the o-rings to replace my old ones since they busted open and started leaking oil again ;(
This is what happend to the rings i got from NAPA
