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?

OEM wires are quite adequate for most setups up to and over 400whp generally.
I prefer OEM over aftermaket when it comes to ignition components (except plugs) in 99% of the cases OEM are of better quality IMO.

When I swapped my car, the clip that I got came with Blitz wires, from the research I did, they are no longer made or sold for the 3sgte. I tested them, and they were within stock specs, so I used them, but when it comes time to replace them, I will get a set of OEM wires.
