T4 spark plugs

[T4Rick]

Can you get better spark plugs with a colder rating?

I think the general Advise is use the genuine volvo ones,

This being said, however, I'm Using the Denso-R Iradium Race grade plugs:

Not cheap but i have always been a big fan of the denso stuff and always try to find a set for every car i own (made a big difference to the performance of my old ford )

Edit: Could always get some champion 701's and save about £5 a plug? ROFLMAO!

Seriously anyone else reading this.... Keep away from those champion ones, they are awful.

The denso plugs look good though mike.

There's detailed Tech specs in a pdf on that page... Compare that to some of the other "Volvo Compatibles" and the genuine volvo ones to see if they'd suit you.

They're really popular plugs with the Scooby / Evo / Tuner types and Very very popular with the Jap OEM's

I melted a plug at the santa pod today so gonna have to sort some out.the denso plugs look good though

I used to use NGK Iridium IXs in my car and they performed brilliantly. I was put of the Densos after hearing about tips falling of them although that was a few years ago.

ok,, i give in, how did you manage to melt a plug? im guessing you'd twiddled something "up" to run at the Pod ?

Yeah... The turbo by the sounds of it.

A rich running engine often runs a little cooler, as it's over-fuelling, If it's running lean, or getting too much air it'll burn hotter..... Enough to melt a plug maybe?

Go on rich... What boost were you running? :P lol

Mmmeeee lol.Ive had the plugs out and they are in good nick bar 1 plug.It was enough to leave a seat cupra r,an evo8,and run in 3 figures with a cossie.I dont no what stage the cossie was though it was quick.The tip has fell off i think but you can see where the plug has melted though.Ive got to take the head off for inspection.Its all good though upgrades will be on way very soon.Ive done a compression test and im down on cylinder 2 in which the spark plug failed lol.Im not mad in any way in fact im very happy by the way it performed.
