I got the car with NGK-R Platniums. Are they the recommended plugs for the S2000? I bought some NGK-R's, and i think they are like v split or something, cant remember off hand, and now it seems like the car isn't performing right, feels sluggish now. Will these cause it to do that?

Thanks in advance

 

get oem ones

 

OEM = NGK Platinum Plus

 

thats not my question, i plan on getting OEM ones when i go to the states next week, just wanted to know if these would make it sluggish?

 

it could have made the car sluggish. we've seen it happen with non oem spark plugs on a fairly stock s2k

 

oem NGK IFR7G-11KS gap is 0.044
