Best Spark Plugs for JDM ST205 GT4 Options

[alex1981]

Hello. I have done a search but cannot find an answer (sorry if I missed it guys!) As titled - is there a general opinion on what spark plugs are best for the GT4 ST205? I have mild mods such as a slightly better turbo, FMIC, boost controller, exhaust and Walbro 255 (which I understand might be w waste of time without other mods to compliment!). I know what plugs are listed as standard fitment - but should I go for a higher heat rated plugs with the mods I have? If so which heat rating? Is there a plug that has been slightly more approved as the best one for these cars in general?

The reason for asking this is that I have not changed them since my ownership (I have not done that many miles) - I get the car regularly serviced at Toyota and they recommend that the next service I replace the plugs. But they want £80 to replace the plugs so I dont think so! Considering for example I can get a set of NGK ones from ebay etc for about £30.

Or am I just worrying about this too much and should I buy whatever the NGK/etc part finders on their websites tell me to get as the standard fitment?

Cheers...that is quite handy as instead of having to search on individual sites it lists all of the plugs

Celica 2.0L Petrol
1994 - 1999 (T200) 3S-GTE GT-4 Turbo FR6DPP22U - Bosch Platinum Spark Plug ( +54 )
BKR6EP8 - NGK Platinum Spark Plug (2215)
PK20R8 - Denso Platinum Spark Plug
IK20 - Denso Iridium Power Spark Plug (5304)
VK20 - Denso Iridium Tough Spark Plug (5604)
BKR6EIX - NGK Iridium IX Spark Plug (6418)


Out of choice...NGK, Bosch or Denso? I would normally go for NGK in my other cars. Perhaps I am just being a bit pedantic about the whole thing, it's only a set of plugs I guess!
