What spark plugs to use for greddy turbo kit?

[Ritz S14]

Greddy recommends: "GReddy Racing Spark Plugs ISO#7 or NGK(colder than factory)".

So, any idea on which Spark Plugs to run? Part # and where can I pick them up?

Thanks.

ngk bkr7eix or bkr7e, its that kind of code but the rest of the letters designate platinum iridium copper etc. the bkr7eix is iridium. I have very hard time buying from parts stores so I just put an order in at www.sparkplugs.com, they were cheaper than other places online and at the stores, at least for iridiums, im sure basic plugs will be cheaper at the store if you can find them.

Just get some BKR7E11 at the store and be done. Gap them between 0.03 or 0.035. Start with the larger gap and if it misses then close it down until it stops.

why does everybody reccomend the 11's which are gapped at .44. why not the normal bkr7e which I believe is gapped at .28 can somone explain, this has been bothering me alot recently.

Ok.. anyone else?!?! Jeff240sx says he runs bkr7eix

I've only had the NGK Platinum stockers work for me. Gapped .30 or something...

I foul anything else with a couple of runs........

dont wanan sound like an ass but there are several threads about the difference between the bkr7eix and the bkr7eix-11. main difference is the gapping. mjjstang is right that the 11's are gapped between .44 while the non 11's are gapped perfectly for .28 or around that. Just someone just recommended the 11's and everyone jumped onto the wagon and started to get those without researching it. ALSO DONT GAP THEM URSELF V!!! u should already kno that gapping iridium plugs will break the tip or whatever u call it. U weaken it like hell and they just end up snapping if u play around wit it alot. If u want more gapping get the bkr7eix-11 and add more power to get a stronger spark or just go with bkr7eix and be safe.

bkr7eix are nice but i have denso iridiums and those are nice :D
