Review on 🚗 Enhance Your Vehicle's Performance with MOPAR 56028138AF Ignition Coil by Charles Woods

This is an OEM product that is a perfect match for our Jeep 4.7 HO engine. I get a repair rebate from my local Chrysler dealer, but it was a few dollars cheaper than their rebate and the dealer was out of stock at the time and it was a holiday weekend. Got it quicker through Revain. We heard a "ticking" noise over the radio relative to engine speed, indicating faulty sparking picked up over the radio. Since there are no spark plug leads (usually a common cause of this noise), the coil and spark plugs are the next places to check. Although the engine wasn't over-revving, the hiss on the radio was annoying. When you come across this, go around and pull the wire off each spool until the "ticking" sound is gone, then you'll know you've found the problem cylinder. Make sure it's not a bad spark plug. Please note that when you unplug the coil cable you are setting a motor code which you can clear or wait for it to go away once the problem is resolved.
