Spark Plugs Running the Daytona Smart Spark on my turbo 5.3, just wondering what plugs you all run? Can you run the standard NGK's like the Br8 or do you have to run a resistor plug with this ignition box? I know plug wires make a difference but I would'nt think plugs would but thought I'd ask.
Depends if you have RF issues with anon resisted plug. The resisted boots are nice! positive snap and easy to position around headers/manifolds. I'd run them just for that alone and to know I didn't have RF issues screwing with my ignition signals. ECU. They are super easy to install too. Then you can run non resisted cheap 8-9-10 range plugs. Thats if you need colder than a 7... If not, just run the resisted 7 plug.

I would ask Daytona tech support if their box supports non-resistor plugs, especially since you aren't really getting answers in this thread specific to the Daytona box.
As for me, just made the switch from BR7EF to R5671A-8 gapped @ 0.020 when I upped the boost to 20psi. Non resistor plug, no interference/tuning issues here to report on stock 2000 Camaro PCM/HP tuners. No noticeable sacrifice in drivability from the 7's. Hell if you can't get an answer from Daytona or someone who's had success with them here, I'd probably just try a non-resistor plug and see if it works with your setup.
Non resistor plugs have more spark energy since they don't have a built in resistor. I'd be interested to hear someone else chime in with a compelling reason outside of potential interference to run a resistor style plug. I would think the additional spark energy would only help you reduce the risk of spark blowout in higher boost applications. I suspect most people (including myself) run or at least have run resistor plugs such as the BR7EF because, well, they work just fine on most turbo LS builds at low to moderate levels of boost.

I Don’t mean to thread jack, hopefully can get some more info stuffed in this one thread though. but I was searching and I seen many recommend the br7’s gapped around .22, I first had them at out the box gap, had issues so tightened em up and now have them about .25 and get breaking up only under partial throttle starting around 3k rpm..initially my PE was engaging during this and dropping the AFR to 11.0 so I upped the tps threshold. It’s still doing it while commanding stoich..is it possible I just need to tighten the gaps up a bit more or is it directly tune related? Not sure how sensitive these things are to the gap setting.
