If you want plugs that don't need to be changed very often, just get stock plugs (platinum) and gap them down to about .032". Note: be VERY careful about damaging the tiny center electrode while gapping platinum plugs...the slightest scratch, scuff, or 'nick' on the edge of the electrode, will radically reduce the service life of the plug.

If you want copper plugs that need to be changed about every oil change, NGK 6097's are ideal for a 'bpu' Mkiv tt, imho...also gap them down to about .032" (depending on the max boost you plan to run, how old your coilpacks are, and whether you have an ignition amplifier (eg. HKS DLI)). Note that copper plugs are MUCH easier to gap than platinum.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
