C20LET (RS Turbo spark plugs)

[A5H]

First off im sorry if this is a silly question but im new to all this

My LET engine has a misfire on idle and after doing some research into it i decided to get some RS turbo plugs

Now the plugs dont match up, the rs turbo plug sits lower than the plug i pulled out

Heres a pic of what i mean

Are they ok to use?

I was thinking the plug wouldnt be close enough to the piston when sparking?

Someone please help me out, thanks :)

Iirc that is so the tip doesn't get as hot to the break down slower. Making them better for turbo cars.

rs plugs all the way cheap and reliable

Ngk bcr9es to be specific....even the big power boys use them. Sometimes don't last very long but the best plug for the job. Best gap is 2-3mm iirc.

Old thread I know but can anyone confirm the best gap for bcr8es plugs in a c20let. Cheers

^3mm sounds fuckin huge gap

I have a brand new set of NGK iridium BKR8EIX if anyone is after some.
Old post I know but for info the RS 071 plugs are very hit and miss quality wise these days.
Also you gap them with the feeler gauges at an angle.
