Spark Plug for turbo Xb ---need a short quick answer pleeese
 

Guys ive bee on here for 3 hours tiring to decide what plug to go get but all I keep getting is answers for either turbo Tc's or NA Xb's all I want to know is what Gap should I go with and if I should run a colder pug? im at stock boost on my greedy kit

this is the plug im thinking let me know what you guys think BKR6EIX -11

most people use 1step colder and since your around 5-6psi of boost it wont hurt.... im not sure on the gap size tho... i want to say 32 for the gap but dont trust my answer for that tho... Lol

hey thanks, hopfully now someone will let me know on the gap lol

anybody???

Use a stock rated plug either 1 or 2 stages colder and at the same plug gap. Thats what I do.

so dont use these BKR6EIX, you say use the stock plug just colder?

On turbo applications, Ive been told to use a plug that is equivalent to stock but 1 or 2 stages colder. That means don't use iridium or platinum.

Get a regular copper NGK plug. They are cheap and usually readily available at any parts store. Get at least 1 step colder. That should be fine and I gap all my turbo cars at .028

Think ill go with what you say, considering you guys build your own turbo, :bow: I’d think you know what you’re talking about lol .28 sounds very close….. Do you mind if I ask why so close since .32 is stock Im not questioning you but just tiring to get the technical reason Thanks

You want a closer gap so that the air doesnt blow out the spark. Anything tighter than .028 wont spark enough.

last look knows the ish lol. just do as he says, cuz i was gunna say the same thing but he beat me to it ahaha. i thought stock was .31, not really a big diff but thats what alldata said when i was in school lol. anyway, goodluck with the boosting

Hey guys thanks allot for the advice, I will be wrenching this weekend need to install my bigger injectors, fuel rail, clutch, and flywheel.... oh and the plugs lol :nails:

well just dont rush things, and if you need it, get hel from someone who has know how lol, you dont wana mess up anyone of those.

lol I hear ya man..... I should be good Ive been breaking and striping bolts for like 15yrs now oh and not to mention all the busted knuckles :D

haha, i hear ya on the busted knuckles, that part sucks so bad lol. but whats worse is some of the bolts on the xb arent very hard to strip, like the header bolts, i had to grind one off of my car, what a pain
