please feel free to add to the list, email Legends702@hotmail.com or post on this thread, will update the .txt file also.
now when someone asks a question that hits the board every day just tell them to search for the search has ended =].
please no dos and don'ts
spark plugs and spark plug gaps: suggested spark plugs:
NGK-BKR7E (6097) aka NGK-BKR7E-11 (1283)
suggested spark plug gap:
.028 (inches) for higher than stock boost applications
.030 for stock boost
how to gap spark plugs:
goto autozone or your local parts store and buy a spark plug gapper for $0.99 and then tap the end
of the spark plugs not to soft not to hard, now start the gapper off from zero and ring the tip of the plug
around the gapper till you get the right settings.

let's also try to get some engine info and links up by engine gen, the common problems for 91 - 92 was a good link, i dont remeber where it was though.

IMO for 99% of owners out there STOCK PLUGS and STOCK GAP are perfectly fine...... customers arrive: "the board says these plugs.. so i did it... says this whatever so i did it... etc" customers leave: "wow -- feels like i have a NEW car!!! soo much more power!!"
eeeehhh -- but what did TOYOTA know when they built these things -- stoopid japs........ **(sarcasm -- not intended to offend my 'rising sun' friends )
Dont forget toyota built these things to run on 7-11psi Not 15+. I once read a that explained why it was better to go one step colder plugs. Ill see if I can find it.

umm -- i have run 20 psi on a stock engine and GReddy TD06 turbo kit using OEM denso plugs set at the factory gap for 2 years.... same set of plugs-- good enough for 12.5 sec 1/4 mi passes @ 115mph.........
sooo -- when are colder plugs needed to make my car run crappier and SLOWER?
PS -- IMO 99% of board members run slower than 12.5 and run less than 20psi boost -- sooo -- IMO OEM denso plugs are perfectly fine and the best choice
gonna try to get more useful links here, lets keep it simple and try to keep the flames down, im just going by what is recommended by most of the guys on the boards, if someone asks questions about plugs thats the answer they usually get, but preference is preference

i'm not trying to flame -- trying to inform as to what does work better VS what also works but not as well or reliably -- the NGK plugs work -- but don't offer near the performance of the OEM plugs or longevity
preference is preference but what works may be different -- i just hate when the folks on the internet post "all knowing FACT" when IMO and the opinion of alot of others the OEM plugs are sufficient for 300whp or less MR2s -- i haven't tried to use them over 300WHP so can't comment on their abilities in that range -- but i do know for a fact that the OEM plugs perform lightyears better than aftermarket plugs at whatever gap "the board" recommends
Yeah I was just trying to point out that coppers aren't necessarily good for everyone. The performance gains are dubious over a set of new OEM plugs and they have to replaced about 10 times (or more) before you would replace a set of platinums.

hehe -- speaking of replacing the plugs -- i just swapped a set for a customer which had been run for 4 years! considering how long they were in there they were in pretty good shape still.......
i agree...stock plug change when bought the car at stock power ..no problem running 289 rite now still no problem..going from 10 psi to 17 then to 20 when i'am moody still perform like no NGK can match
