Best Spark plug for Volkswagen Corrado

I typically run the NGK Iridium plugs. Plug number: BPR6EIX I have run them for a long time and I love them. I messed around with different heat range plugs but for a stock alternative, I love them

I've been using Bosch FR8LDC in my car for years with good results.

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

Yes the 5's are colder plug But they run great and less fouling out.

We both run Autolite Platinum and they fired up no matter how cold it is on the first try.

car has been running with champion plugs so thats what i put in and it reved to 6500 just fine......the car likes the new stuff i put in a lot.

They have 2 electrode and yttrium content with copper core. First, the car idle better now than with USED NGK 3 prong spark plug.The idle is lower at 800rpm(new spark plu gap) compared to 920 with NGK (bigger gap) The stock spark plugs were hafl used, white-black color but with some yellow tiny dots on electrode surface whats this ???? I went for a run and these spark plug are not made for high rpm use.. The engine noise is metallic above 4k and it doesnt pull like used but in shape NGK plugs. The spark plug gap is too small I think. I will check my mpg and report this later.

Apparently these are good for my race car but might not be good for street application.

I too happen to have the champion plugs that iceman has. Happened because Murray's didn't have the dealer only replacement plug and couldn't get them. I had no choice because the stock ones were blacker than my tires. They rev just fine and seem to run just as well. I was told that a long time ago champions were known to become permanantly stuck in the block though. I plan on changing soon just in case that rumor is true.
