What RENIX ignition upgrades are you running?
Where did you find Said upgrades?
And have they made a difference?

Subbed'

From a fellow renix owner,I think there needs to be more renix threads.

Me too

Me 3 lol

Me 4. Don't waste your time. NGK plugs, Napa Belden Premium wires, cap and rotor with brass terminals. As good as it gets. Aftermarket coils are prone to failure.

Do this:

Renix Jeep ICU/Coil contact refreshing
　
　

The contacts between the coil and the ICU on your Renix Jeep can become corroded and loose causing a complete or intermittent no-start condition. I recommend the following procedure as a maintenance precaution to insure this is eliminated as a possible cause now and in the future.

The coil is attached to the ICU by two T20 Torx bolts. Remove these two bolts and lift the coil up off the ICU. You will see 2 pins and 2 sets of contacts. Clean both the pins and springy contact pieces with a good electronics cleaner.

Squeeze the springy contacts closer together with some needlenose pliers. Apply some dielectric grease to the contacts and bolt the coil back on to the ICU.

While you’re right there unplug the connectors from the ICU and inspect the pins in the harness connector. Make sure the pins are not retracted into the connector. Spray out the connector and the receptacle of the ICU with the same good electronics cleaner you used earlier. Apply dielectric grease to the connectors and plug them back in.

I feel this procedure should be performed at least once in the lifetime of a Renix Jeep.

Why are they prone to failure...?

Poor quality I guess. So, you spend money on something to improve your ignition system. It doesn't, and has a higher failure rate than standard parts. Not a good deal.

Where are you getting you info from that the Performance Coils fail more than standard parts. All they are is more Copper wire coild in the unit...

Well I mean is that your Opinion or fact. I just cant see all Performance Coils being more porne to failure than a regular one from NAPA or where ever... Plus the Performance ones seem to be the same price as a Quality coil anyway....

From being on 4 or more Jeep forums. Guys wanted to improve their ignition. Bought the coils. They failed. Went back to stock.
