Alrite found some Ik20 plugs for my IS200 on US ebay but for other Lexus models eg; GS,ES,LS only had IK16 plugs. Am just wondering will they fit. If not the cheapest place to get them please. Thanks

if ur asking will IK16 plugs fit - yes they will but it wont do the engine any good, if they are too long you will put a hole in the piston, if too short wont run properly and even if its the right length its the wrong heat range

have a search for sparkplugs and u will get quite a few topics along with some good ebay links.

All you need is 6 Denso IK20 spark plugs. Your best bet is to buy them from US Ebay, thats where i got mine from.

Alrite found some IK20 one but for another Lexus a GS will they fit?

as above - an IK20 is an IK20 regrdless of what car the advert says.....
