Spark plug Bosch or Motorcraft

I've run NGK BKR7E's, NGK BRK7IX's, Bosch FR7LDC, and Bosch F7LTCR's. Of all of these plugs I noticed the best performance out of the F7LTCR's.

I switched to a Bosche plug F7LTCR $4.41 a piece from rockauto.com. They last 4 times longer, and run much better than the BKR7 series.

Bosch FR8DS plugs are stock aba (2.0L 8v) plusgs and are awesome.

VAG engines seem to like their factory recommended Bosch plugs better than any other.

I used Bosch W4CS (cheap plug) with good results in my G60.

I just replaced my plugs in an 89 16v yesterday. I ended up getting the Bosch platinum +2. I was leery of the platinums as everybody seems to knock them, but my car runs fine. They were 4 bucks each.

got my f6dtc's at the dealer (only place i could find them), and they were around 4 bucks a piece. car ran like a dream.

You do know that a bosch "7" is 1 range HOTTER than stock and 2 ranges HOTTER than a NGK"7"

I have a strong opinion in not suggesting the Bosch or the Beru. There is a reason that BOSH is no longer the OE spark plug in VW, Audi, BMW, Mercedes Benz etc., etc... Stick to the NGK, especially in a VR6, NGK has been OE since the intro of the VR6 six months after Bosh failed to produce a plug that would run in these engine during start up. The Bosch had nothing but running problems.

And I tried both the Bosch and the NGK back to back, and the NGK ran far better than the Bosch. The Bosch were terrible in my case.
