I used this info from the hatch thread. Hope I have the right ones now as cars in on Tuesday to get them fitted
Yes they are for a 2.5 based engine that has deeper plug holes to stop the cracking round the plug hole issues on the earlier 2 litre cars. However raggy has a 2 litre based engine so it is not the correct info for his, he as correct info already
Ilfr Plugs are a lot longer than the prf ones so I'd make sure there right either way as when I got my hawk someone had put the wrong plugs in so when I had it service st the garage they just replaced what was in there , then I looked and found they had fitted the wrong ones
