just bought the stock ilfr7h plugs..do i need to gap them before i put them in?

 

yes gap is to be set at 32 or you can set it a little lower at like 29-30 and it wouldnt hurt

 

ok..what if i just put them in without gapping? im not going to do it but just curious?

 

well it may not run correctly. even if they come pre-gapped i always check them myself to be sure that they are correct. not having the correct gap could cause spark problems.

 

ok thanks

 

Fixed

 

Here is a good thread with your answers in it..

READ THE IX MANUAL.

I don't believe .032 is the gap for new plugs!

I think the manual says to gap between .021 and .024.

The IXs use a diferent gap than the VIIIs, stock.

 

And a different plug

 

DO NOT GAP at .032 They need to be gapped at about .022. The IX iridiums run closer than what the VIII do. Gapping is not required...alot of times gapping the plugs will break the iridium tip. Mine came gapped out of the box at .022 which is about perfect.
