the plugs are autolite platinums AP3924. the wires are the blue ignitors from techtonics. the rest of the ignition is stock. do i regap the plugs, or should i leave them where they are now. i'm leaning towards leave them since it ran fine before and i don't want to deal with a no start issue when i start it or the first time with the new cam.

i have been using the W7DTC plugs and they have been working great for me..my car is always held way up in the rpms..they have never fouled out or caused me any problems..and i get 8 of them for 30 CDN... seat of the pants tells me i like them better than my old platnums..the car idles better with them.. they are worth a try
I've been running W7DTC's for about a year now, with no problems. I haven't done any back-to-back dyno testing to see the difference between them and the usual W7DC's, so I can't comment on any power losses/gains.
I have never had an issue with the Bosch's
I personally pick the Bosch Super Plus Copper because they are cheap and last about 20-40k miles...
I have a full obd1 wiring harness from box out 1 brand new plugs(bosh)wires(bremi) cap&rotor(bosh) bucking is not as bad
After too many bad experiences/unhappy motors I wouldn't put bosch plugs in a lawn mower.
I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak
I took a peak at mine the other week and the gap was HUGE so gapped them down to .035 and now cold starts are ROUGH. The pugs in there suck, anyway - old autlites.
