want to fit new ones in my 20vt 1997 was thinking of uprating them! which ones are best and how much they come?

Meagy

Standard plugs: NGK BKUR6ET, uprated/colder plug: BKUR7ET, even colder is 8ET and so on. Iridium plugs end with IX or something similar I think.

Sorry to jump on this thread but has ANYONE on here ever used the 8ET's at all??

Am just wondering if they could be even better for my setup with LPG

no, they would be too cold IMO.

the 7's are good enough, and only really for higher boost apps.

The thing is with the research i have done LPG burns hotter in cylinder anyway so im thinking with even more boost come the summer time i could see higher temps, even with the PA FMIC.

You think im better off seeing what i get on the setup of the ecu after the new bits are put on??

Agree 7's should be good enough, the problem going even colder is that on cold days the engine can be quite hesitant till the plugs warm up

Joe

will these fit?

Yeah, but you'll lack one plug.

are they the right size i.e. thread etc?

Yes they are. I belive it's the first letters in the NGK product code (BKUR) that tells you that they'll fit.

thats is cheap for a set tho isnt it???

Just checking but I take it you run a colder plug if you are running more boost due to the extra heat in the combustion chamber? So if I was to run 1.2bar with a Pace WMIC it would be better for me to run BKUR7ET? Looking to fit a new set of plugs before my Unichip install and want to know which would be best?

thats what ive been told mate yes!

Take a look at your current plugs, if they look okay (golden/light brown) and the car runs fine there should be no need to go colder.

wheres the best place to get a set of these then lads NGK BKUR7ET??
