What Oil Should U Use? And Spark Plugs ?

[Ekul]

Just been having a look at the Iridium NGK plugs that are mentioned in this thread - Repco want $32.99 each for them, but anybody can get them off Amazon for just US$6.95 each - what is all that about...?

They seem to be listed under 2 NGK numbers - not sure if they are different plugs, NGK BKR6EIX and NGK BKR6EIX-11 - maybe somebody can enlighten us?

Does this plug really make that much difference at the cylinder pressures generated by vehicles running just regular 98RON or less? Would just the standard plug correctly gapped and in good condition be just as good?

BKR6EIX-11 = 1.1 mm gap, whereas the BKR6EIX = .8mm gap.

I only changed mine to the .8mm because I didn't realise the BF has .9mm gap from factory whereas the BA has 1.1.

EKUL,I got my NGK plugs from the USA cost me $55 delivered for a set of 6.You need to get NGK BKR6EIX p/n (6418)pregapped at .8 The other ones are gapped at 1.1 .if you running more than stock boost you need to gap plugs at .8

Why so KABOOOOOM...? No problem for a strong late model engine.

Peak at 17psi hold 13psi under hard acceleration - by the time peak boost hits and you fell the really strong acceleartion the vehicle is already going over 140km/hr. Its not like you are going to drive like that too often. The boost starts to falls off before limiter revs.

Not exactly boosting at 17psi all day and everyday - just got to mind how you go and be sensible with it. Make sure to only use 98RON if driving hard - maybe add 5 litres of toluene...

Anything generic should be thrown in the bin. I hope you at least have had it on the dyno to check your AFR's. I do believe the fg's have weaker internals than the BF mk11.

I'd hate to see you blow a hole in your block.

I had been running staned platnum plugs in there they lasted 15,000kms geeeee lol what a waste of mopney they should of lasted around 90,000kms ppl tell me any way I changed to the .8m gap and geeee my car goes and goes and goes some people say it doesnt make a difference but I saw the difference

as far as the oil goes I can try 10w-40 ful syn in my car and it will run better I hope

just grab BF ford plugs and regap from 0.9 to 0.8 and I use the oil which castrol and nulon recommend as their No 1 choice for XR6 turbo and F6 which is 0/40

Why would you do that when you can just buy the pre-gapped plugs?

Fully synthetic Nulon on my Tornado. I was using Mobil (fargin expensive), but was recommended Nulon by members on this forum. Alot cheaper cheaper then other brands.

[Adam]

Agreed.

I buy it in 20L drums and it's MUCH cheaper than a lot of the other brands.

Cause the plugs are $7 each and good enough for my 500HP
