The Definitive S2 Spark Plug Thread

[johne]

If they have it'll be because NGK have given VAG a better deal than Bosch.

Years ago when plugs where changed every 6000 miles it was said that Champion gave plugs to BMC & Jaguar for free just so people then used their brand for servicing for the rest of the life of the car.

also have VAG dropped bosch for ngk on newer cars?

[GazzaG60]

not an easy one plugs. the standard plugs are rated very poor on some us forums with proven issues of broken electrodes etc.

i have at present bkr7e. working fine. gonna try another soon to see where it takes me. gapping is probly as important.

Tryin out some Laser Platinum NGK PFR7B... only been in a day, but so far feels really responsive... but then after looking at the ones that i've taken out anything'l be better!

Anyone know anything more about these?

have i made some grave mistake...

The good book states 0.6mm (with tolerance permitted up to 0.7mm)

[vonbeck]

Can anyone tell me what is the gap between electrodes on F5DPOR?
0.6 or 0.8 mm?
Thanks,
Costan.

ditto?

2 of them were loose. You could easily turn one of them by hand. Hopefully that is the problem then!

[S2central.net]

YES - sorry for not thinking of it sooner mate... I've never had a plug so loose that it whistles, but I would get the injectors tickled properly anyway - however - would be interesting to see what difference is there with plugs torques up again... All good stuff in the search for root cause !

[stevieyid]

Got the injectors off at the moment was going to get them sent off today. might put them back on to see if that has cured my problem. Could that be a cause of the whistle?

[S2central.net]

Ahhh - S2 ownership 101 - how is she driving now - still got whistly noises ?

[stevieyid]

Just fitted my spark plugs and sure enough 2 were loose. Will be checking them more regular now!

[GazzaG60]

BK7re is what im running.

found the standard plug a little to hot in modded engine.

Personally ive had nothing but trouble running the NGK plugs and mine runs alot better on the Bosch ones

My car is running with NGK too,for a while I didn't had any problems,but for a month or so my car is not running good..Today arrived f5dpor,monday I will change NGK with Bosch.
For the reccord,f5dpor is with one electrod,you know that,but f6dtc,the one if've wrotten earlyer,is with 3 electrods.
Because I've founded only 4xf5dpor i've bought 1xf6dtc,next week i will get to other one too.
Cheers!
