Bought and fitted some denso ik31 spark plugs to the sapph today as recommended by yourselves, bought from motorsport developments, excellent service from them too.
She idles better and just feels stronger through the gears than she ever did, had the pp8's in for years but these have made a big difference, cheers lee.

 

Two gentlemen who have a wealth of knowledge nice 1

No probs m8 , share the knowledge .

 

So are these denso plugs the best then cause ive had the ngk irudim plugs in for 2 years now and these have been spot on.

 

Strange this, i put up a post about these plugs.

I also run the pp8s at present, so after reading this i will be getting some ik31s

Steve.

 

Got one right this year, yaahaay.
Glad it works better anyway, I have these in at stage 1, just till mapping on 15th though, getting well excited now, like a kid waiting for X-mas!!

.......glenn its like everything on here..........OPINIONS vary...............i had denso's........they shit themselves.......i've used ngk's for 2 years with no probs..............if ur happy with what u've got,then stick with em...........

 

Well its like that saying goes if ts not broke dont fix it.Pete 1 of my mates said you look the spit of phil colins lol.

 

Ive had a few cossie's now and i must say that plugs that have worked fine in one didn't in another, however these denso ik31's on my stage 3 sapph work great and without advice i would have just stuck some more pp8's in as i agree that if it ain't broke don't fix it, it now drives better than ever, i even had a strange boost problem that nobody has been able to trace and that's disappeared so maybe it was something else, very happy now.

 

How much are they?

 

£39.99 from motorsport developments, i got mine from them off ebay, they seem a little more expensive elsewhere, seen them at £54 from one place.

whats the differance between ik27 and 31's as Karl at NMS put 27's in mine?
