Whats the correct spark plug

[dadnkid]

Hello all,

Just bought a 99 Spyder GST. Checked the spark plugs and the part number is BKR5EGP, made by NGK. I checked NGK website and they show it for my car but, ran a search on here and it's not mention anywhere. Most are running NGK 6ES for stock. The tip is white which many on the internet say its the wrong size, not correct heat rating, or the car is running Lean. Any help would be great. The car is completely stock. It needs a lot of work but thats for another post...or i can explain here if needed.

ngk bpr6es gapped .028-.032

People use 6's or 7's...And gap can vary between.24 and .028..I know the manual says.032 but I've never had a problem going with.026....The higher the boost the more you can go down..

So is the BKR5EGP wrong or just another plug. I know everyones prefer the bpr6es but can I use the ones I have? the ngk website is messing me all up. I inserted the link to the website.

Go with the 6's. 5s are a hotter plug which is probably why the tip is white.

That link is for a 4g64 engine, not 4g63..
