Ignition Coils... OEM Versus High Performance Coil

Asked by Dec 26, 2015 at 05:48 PM about the 2005 Scion xB 5-Door

Question type: Maintenance & Repair

Am I really gonna get better performance from my car using an Eccel ignition coil over an OEM replacement coil. I can get 4 OEM for $100 dollars down the street today. I can get 4 Eccel's for $200 dollars on line but have to wait for a few days is it worth the extra money and wait. I have no problem waiting if I'm actually gonna get real performance improvement Thanks

There is a performance improvement but only in the higher RPM's and the coils ability to deliver stable voltage at those RPM's, if your not into Gymkhana or something similar High Performance Coils might not benefit you any, plus there is the spark plug life, if you go with the performance then you will have follow up with the performance spark plugs also, otherwise the coils will blow the tips right off of the plugs.

Ditto, I could not have said it better except I am not familiar with Gymkhana. But I can guarantee tennisshoes knows what he is talking about. But it's a Scion...? What do you expect from a shoe box on wheels? I just don't get it? What is wrong with the coils now?

OEMs are usually the best. Fords have the same issue, OEMs work the best others are iffy. OEM Ford coil on plugs will support over 900 HP. Now I know you don't have a Ford, but the same thing applies. The car makers today make a pretty good product. Their high voltage ignition systems are top notch. There are other ways to make more power and the Accel coils are not it. Do some "Googling" to see what others say. Ask for a dyno chart from Accel on the supposed gains. A quality cold air intake will do more and likely cost less.
