600 mile Review. PumaSpeed coil packs are a great replacement over OEM coils. Power is more smooth and far stronger than stock coils seemingly across the entire RPM range. Idle is pretty similar to stock. However once you put your foot down you do notice the difference. I did swap OEM and PumaSpeed coils back and forth to be sure it wasn't a placebo effect.
No regrets purchasing the PumaSpeed coil packs. I am very happy with these.
