What is the best spark plugs to run on the turbo?

 

what stage and company are u getting or have?

 

I just bought Denso Iridium IK22, heard good things about them but they are in the mail should be here tomorrow

 

I run ik24. Turning out to be the perfect choice for my mods / boost level.

 

Regular ngk gaped to .035

 

can someone show me a link to get these. I searched but I dont know if they are the right ones

 

Which ones do you want? I can get you a link

 

Desertheat......could you tell a difference between stock plugs and your IK24's? Also what do you have them gaped at

 

They are gapped at .035. As for a difference, start up was much better running iridium and idle is much better. Under WOT I am not skilled enough to tell a difference because it would be to small for seat of the pants dyno. I can tell you that my stock sc plugs that toyota gave me were crap. They already had electrode wear that was noticable at 4K miles. I have checked to see how the plugs are doing being a range colder than what TRD supplied and they dead on.

Your stock plugs are iridium already, and unless your boosted, stick with them! If you are boosted at least go 1-2 ranges colder.

 

I just got my Denso IK22 which is one step colder, is what im told. Yes i am boosted, with turbonetics. Gonna install them tomorrow. Should i just leave the gap how they came or should i change it. And after i get them put on i'll post on how they feel

 

ik22, leave it alone. It is already set to .035

 

I just need alink to see some spark plugs, I tryed searching but I mean I dont know which ones to get.

 

hey i just got the NGK iridium IX BKR6EIX-11. on the paper it said not to GAP iridium plugs because you will snap the center electrode. I dont know what gapping a sparkplug is but thats what it said.


can i install the sparkplugs without having the turbo on yet?

 

You can gap the iridiums, i just did with my Denso's. But you HAVE to use to old school gapping tool. You CANNOT use the round gapper. Just go to an autoparts store, they will help you out, maybe even gap them for you.

 

I'm running Denso Ik22s on the Dezod powered tC. Never changed the gap.

 

but can i run the sparkplugs on my tc without the turbo? like will anything bad happen?

 

Well i gapped mine to almost 40 but now im having second thoughts about that. The Denso's i believe are a colder plug, good for turbo's but im not sure about running them without turbo. Dont know what the effect would be.

Im thinking about regapping mine down some. Im just not sure what exactly to gap them to yet

 

They say not to gap them because some people still use slide gapping tools instead of a feeler gauge. The iridium tip on NGK are .7mm and on denso they are .4mm and will snap with ease. If you snap a tip then they are toast. Also the bkr6eix-11 is a stock heat range plug and is also pregapped loosly to .044 which I would not reccomend. You need to be running a bkr7eix or even a bkr8eix which are both set at .035 loose.

 

man, i asked peteyd which spark plug he reccomended and he said the bkr6eix-11 are perfect, especially since i wont be running anything with the turbo except the e-manage.

 

Well he told ya wrong. Stock heat range is 6 in NGK or 20 denso. Stock plug is already iridium and an IFR series which is a much nicer long life iridium than the IX series which is geared more for sales volume / performance... so you wasted your cash sorry man.. Performance wise you cannot tell the difference between a stock IFR6T-11 and a BKR6EIX-11. Just the stockers will last longer.

You should be 1 range - 2 ranges colder running boost and gapped tighter. The plugs you have now will work fine but they are definitly not gapped right for boost. They will still fire and run correctly because iridium plugs are very efficient at setting a nice arc, but they are not optimal. Again bkr7eix or bkr8eix would have been the correct choice. Or if you fancy denso.. an ik22 or ik24 would have been perfect for you.


How do I know? I made a living for 4 years selling nothing but spark plugs and was / still am a spark plug specialist for many race teams worldwide, from the salt flats to the drag strip. I know most all plug numbers off the top of my head and know most applications off the top of my head, I am in short, a spark plug expert... not trying to sound high and mighty, just happened to be a profession for a long time and still is haha. I still am an NGK dealer and also a Denso dealer. But I am not offering to sell plugs on here, I just mainly do them in bulk qty for race teams on the side now.
