Which plugs


Keith C

Recommended Posts

At 69k miles, my plugs are probably due a change...:twak:

 

So, as I'm running increased boost (due to that impossible to find air leak, officer), up to 1.2bar at peak, I've been told I should go a grade colder than stock.

 

Is this right, and if so, can someone give me a part number for the NGK's I need?

 

Cheers

I can't tell you the part number for NGK's but i think the Denso's that Alex supplies are pretty good. I would go for the IK22 or 24.

I'm running NGK's BKR7E's at 1.2-3bar. Sweet

Well life, I'm not too fussed about - provided they last relative to their price - ie a cheap plug I'll happily replace every 9k, a mega expensive one I want to last a bit longer.

 

Denso's are the factory fit jobbies (which, interestingly, show *perfect* wear for their age, mileage and use, which is nice), but NGK have always struck me as a classier brand.

 

However - Alex - how much for a 6-pack of Denso's?

 

Shiny doesn't bother me, cos as a superior UK-spec owner I'm above such pettiness :p (Joke! I'm drunk...)

I'm "ON" PFR7B's at present....

 

same "1-grade-hotter" as BKR7E's but Platinum...

 

Left 'em set at preset (~0.7-0.8mm) 'cos me old ones gave

 

nasty hesitiation at ~6,000 under load ....

 

No probs so far (other than the PF's are ~twice the price of BK's)

 

FatS.

 

[ps. MATT reminded me about the 'gapping'...... he'll get pissed if

I don't give the 'credit'....:p ]
