Doesnt the manual/book for the brand of sparkies tell what the gap is?

Probably, but if you are running a little more boost that is no longer relevant. If your running stock boost then you could prob get away with 1.1 gap which is what they will most likely come with but running .8 wont cause any issues anyway.

You should get BKR6EGP instead and gap to spec, btw the difference between number 5 plug and 6 plug are 70-100'c. You could be running too hot in your turbo engine.

What gap are you running on your iridium?

Well I dont have anything to measure the gaps with but they look stock to me 1.1mm. Quick Question so wht do the different heat ranges do to or for the car?

The bigger the "number" for NGK, mean the more heat it will cool the combustion chamber.

Try gapping your plug down to 0.8mm.

The gapping tool will look something like this.

      Unpeeling the Orange

      By MBS206 · Posted

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
