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.

Pros: better idle, lower idle

Cons: not for high rpm, metallic engine noise, less pull

Vehicle: Volkswagen Corrado

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.

Pros: best performance

Part number: F7LTCR

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.

Pros: last 4 times longer

Part number: F7LTCR

After I put them in (I was one of the first in my region to carry them and use them in my own car) I found a significant loss of power. Swapped those puppies out for some Bosch Supers and I was back to where I was before I put the Plats in.

Pros: Bosch Supers work well

Cons: significant loss of power
