Ive been trying to find some info on some coils im pretty sure i need to replace mine. Oem seems to be the right choice, but wondering if i should just upgrade to a better coil. Anyone have some input.. Car makes over 400 and boost wise is about 18 to 22. I heard and read that the spitfire dont like 21 lbs or more.

 

No. Splitfire is a good coil pack to run... OEM coils are hit or miss.. I have ran fresh stock coils to about 750 rwhp .. which was 30 psi on a 35R and a 100 wet shot. No misfire... and then sometimes I've had to replace them as low as 300 rwhp on older motors. Splitfires work well under any conditions you could give your motor.

Nobody is running anything different on there setup?

 

It's either stock coils, stock coils on a voltage amp, or Spitfires.

I run my Spitfires on 21psi all the time and I never have a hiccup. The coil pack upgrade also smoothed out my idle and low-speed response. I can tell I'm getting a more complete burn because I don't smell like exhaust/fuel as much anymore! haha. It's a great all around kit.

 

thanks for your input.
