Thats not bad for a set of brand new coil packs... they will probably last another 15-20 years, coil packs are important

If you're going to get new coilpacks, you should look into Super Spark coilpacks.

I wrapped the stems of my existing set because I'm poor so it's been a long temporary fix. But eventually I'll get a new set and wrap those too before any problems arise.

Are you guys talking about cutting out right when full boost is made or up in the RPM band? Sometimes my car likes to cut out at the top of each gear. It breaks up for a split second and then goes right back to hauling ***. Is that a coil pack issue or is it fuel cut..its possible im getting just above 14psi
