hello .what is the right gap for the bkr8eix ?

 

0.6mm-0.7mm

 

many people say that has to be 1.1 as oem . i m very confused. the bkr8e-11 is a better choice for s2000? thank you

 

OEM gap is 1.1mm as noted in the OEM plug part numbers but if you're still running a much higher compression ratio than stock your gap will need to be smaller for max performance.

What's the gap on these out of the box? Diddling with the gap requires keeping the ground and center electrode parallel. I've seen cautions to not alter the factory setting by more than 0.008" (0.02mm) which is darn near microscopic.

The plug is designed to run a 1.1 mm gap to have the ground electrode parallel to the center electrode, hence the 11 digits on it. If you buy the pre-gapped version it will come at 1.1 mm gap. Some of the NGK IX plugs can be bought without being pre-gapped, so you can gap them to 1.1 mm or whatever you prefer. Many people can't gap plugs with fine wire electrodes without causing damage, so NGK recommends not gapping them, but I've done it for years without any issues, you just need to do it right.

 

Strange mine have always come gapped around ~0.7mm +-0.1mm for those plugs, nowhere close to 1.1mm

 

yes they come around to 0.7 mm .
but s2000 need 1.1mm in oem sparks.

so you gap the bkr8eix to 1.1 or u use them as they come?
