i have an spi cooper (1998) which plugs does everyone think are better and has anyone played around with gap sizes? i am currently running ngk bpr5es with a .080 gap - are champion better? i know iridium are better but are they ok in an spi mini? - i look forward to everyones thoughts - mark

On my 96' SPI I've been running the BPR6EIX Iridium-X NGK's. Gapped at .80mm gapped. works perfectly.

do you think it would be ok on a distributorless model? i have read that they dont like extreme plug changes, is that true or just a load of #$%$#@#$$% - cheers for the reply

actually i also have a 1998 MPi Mayfair that i run with these BPR6EIX's as well and it runs very well. I have these gapped at approximately .85mm

you have be be VERY careful with gapping iridium plugs...they do NOT recommend it since its very easy to snap the heads of iridium clean off....but if your very careful its OK to do...i'm a rebel i guess.
