hi,bought the ik31's but the number on the ones i have is-itv20 5339 and they are a tapered seat,are these the correct ones?have never used them before so dont know if they're right,was about to fit them,will leave it just now tho,any help appreciated thanks col93saphcos

 

NO STOP!!!!!!!!!!!!
Tapered seat defo not the right plug, the correct plugs have a normal seat with a little seal on the bottom(round ring bit).
