I used the bosch filter anway because I had already purchased it. It has a release valve, Fram doesn't. Anyway the Bosch o-ring was thicker and softer than the Fram's. Hmm, I bet that's why it was leaking.
Pros: has a release valve, thicker and softer o-ring
Vehicle:
Volkswagen Corrado
Bought the Bosch last time and they are great.
Pros: great performance
Replaced both wipers with a Bosch wiper and arm that has a little window that changes color when needs replacement. Works incredibly well, and so quiet, no chatter or streaking on either side.

i had a buddy purchase me a set of bosch platinum plugs. i installed the plugs this morning before going to work, removing the old plugs, i found the number 1 and number 2 are wet with fuel. after installing the platinum plugs, i cranked the engine. and it started! the idle was smooth. i took my vw to work today, and the engine pulled smoothly in all rpms!
Pros: smooth idle, engine pulled smoothly
Cons: old plugs wet with fuel

I got W7DC spark plugs from the local foreign parts place...performance hasn't been ideal, and I've already looked at some of the other common issues; I'm considering new plugs in part due to fouling (bad CTS, drove with a failed CTS for too long, lots of carbon on the plugs...cleaned them up some, but I'm not convinced they're OK).
Cons: performance hasn't been ideal
i have never heard a good thing about the Plus 4's, lots of the VR6 people stay away from them. one of my VR6 buddies had some that were trashed in a short period, nothing wrong with his car just the VR didn't like the plugs. i have had them in my Frontier and pulled them out after about 10k miles they looked ok but truck didn't like them. yes they were gapped correctly, went back with the NGK's that were OEM and truck ran better. better how? smoother, no hesitation and all i did was change plugs back and forth. nothing else was done to the truck. i know this post is vague but i don't have any techie stuff to back it up, what i am baseing this post on is experience with my Nissan and witnessing what my buddy had happen. yes the plus 4's have a lifetime warranty and are not that pricey, but i'll bet you won't notice any gain on mileage or performance, unless your current plugs are way past their prime.
Pros: lifetime warranty, not pricey
Cons: trashed quickly, truck didn't like, no gain performance
