Thanks !!

What does the book say. Manufacturers spend a lot of time testing various items for their engines and what they recomend is probably the best way to go. On the other hand i'm a big fan of the Bosch Super 4 plugs. They really do improve the cold start performance

tbh, this is the kind of thread in which you'll get a billion different replies. The last set I put in were actually volvo brand ones, but lots of people use NGK

super 4 the win lol

they own!

Only only use three different types of plugs on LPG as you need a better spart

Volvo plugs
NGK V groove
Bosch single core plug

Just put some NGK in mine... I don't think you'd go far wrong with the brands suggested.

Amen to that dude! Work an absolute treat in my F7P

NGK V-lines (BPR6E) in mine too ...

According to Haynes, Volvo increased the change intervals from 10,000 kms (6T miles) to 20,000 kms (12T miles) in 1989. Strange, that ...

maybe they got better?^ things seem to work much better and can last much longer nowadays, just look at the differnce in oil! it lasts, stays cleaner longer and even stops the engine seizing used to have to change it a lot more! and it would still let the engine wear as it moved away from the metel/pieces incontact.

also super 4's people that dont like them dont like them becouse a, they cost more and b, they have never tryed them.

Don't get me started... I think theres a thread on here in the depths with me ranting about super 4's. The only advantage they have is slower wear rate!

EDIT: Thats not to say they are bad, just don't believe half the hype people will try to have you belive with them.

The super 4's can give very slight (1 - 3 BHP) power increas but I keep well clear of them for a number of reasons.

1) I have known them to fail as in not work out of the box
2) missfire problems
3) over prices
4) Does not work with LPG

sorry i dont know why i get so... set on getting a point over its only sparky plugs any way... i guess

but i do believe them to be better than splitfire plugs and other so called "power boosters" the main thing with the 4's is that they are silver plated (which is the best conducter ) platnum isnt that great for conducting but lasts, copper is good also!

volvo ones are good, reliable etc, i have found that any make of plugs can not work when you get them, they may have been droped or any thing.

Denso Iridium IW20's FTW - made a big improvement to my B19E, and I don't care how many people say a spark plug will not help performance...

Could we have some part no.'s people??
