Ngk iridium and denso coils. Theyre the oemChecked my spark plugs and they are looking quite worn. My coils also have cracks in the plastic. Any aftermarket stuff I should go for? Should I stick with OEM? Im going for Gas milage over performance if that narrows it down a bit.
So.... whats the point of ur post exactly? I dont recall the OP giving a crap about ur alternator or starters.2 out of 4 original DENSO ignition coils are still running smooth in my car after 335K miles.
The slightly cheaper off brands lasted only 20K miles then started misfiring. A Bosch and AC Delphi coil are still in the car running after 60K miles.
Why take a chance, waste time and headache. Buy direct from DENSO you will have authentic parts, the most reliable electrical parts at the lowest prices in the market.
DENSO also sells reman starters and alternators cheap. DENSO's reliability is unbelievable. My original DENSO alternator after 330K miles stopped charging. The carbon commutators wore down too far, not making contact. Bought them for $6, screw them in, the alternator worked perfectly again.
Go to the parts store and buy ngk iridium plugs. Theyre pre gapped, just put them in.Alright, Thanks for the input! Ive decided that I will keep using the current OEM coils I have because they work fine enough, and NGK or Denso iridium plugs. Im not sure what kind of plugs I will go with tho, as I dont know much about NGK and Denso has different variations (iridium, iridium TT, iridium long-life, etc). Any recomendations there? And what about gaping? Stock or just a slight lean twoard one side or the other? They will be going into a 2ZZ.
Looks like a OEM Denso plug hehe. The original plugs in my car were Denso Irridium, lasted over 200K milesIf you want OEM spark plugs, this is the part number: 90080-91180 - Spark Plug - 1992-2012 Toyota | Boch Toyota South (which I believe are SK20R11)

Alright, Probably will get those. I have 2 different spark plug part numbers in right now and im not sure why. Both are denso and are 1 letter or number off.Looks like a OEM Denso plug hehe. The original plugs in my car were Denso Irridium, lasted over 200K miles
There were reports NGK plugs did not run well in Toyota products. To avoid wasting time and headache just buy the same original components that came with the car from factory.
Stick with the denso iridium. The wrong plug can mean disaster !!.....led me to a rebuild !Checked my spark plugs and they are looking quite worn. My coils also have cracks in the plastic.

2way said:Denso Plugs:
GT = SK16R11 Stock OE long-life Iridium, IK16 "Power" Iridium
GT-S = SK20R11 Stock OE long-life Iridium, IK20 "Power" Iridium
GT = IFR5A11 Stock OE Laser Iridium, BKR5EIX-11 "Power"
GT-S = IFR6A11 Stock OE Laser Iridium, BKR6EIX-11 "Power"
The Densos & NGK's are essentially the same plugs... the major differences are between the SKs & the IKs/IFs & the BKs... the SKs & the IFs are long life versions with slightly larger tips and have platinum ground electrodes that the Power versions don't have.
... ur spark plug will not make ur car more powerful or faster. This has been proved agian and agian. Nor will there be any performance difference from platinum to iridium other than how long the electrode lasts.I love my 2000 GT....but I also have a 2001 Corolla with the same engine ( 5 speed manual) that will beat the pants off the Celica...huhuhu. before rebuilding the Corolla I burned an exhaust valve, actually blew a pie shaped piece off of it. I was using Bosch platinum spark plugs....a mech told me to switch back to Denso Iridiums. The car is a rocket now to the point I laugh when I drive it....stick with Denso.....
