Pinging ...Spark Plugs
JK Wrangler, done 20,000kms and pinging getting worse
Changed the Champion RE14PLP5 spark plugs, manual says change at 60Ks
Same hill, same fuel in tank, ron 95, same gear, no longer pings.
Tried again, higher gear, no ping and does the hill easy.
Used cruise control both times to take my right foot out of equation
Research on plugs,
Bosch, NGK, Denso, NGK recommend one heat range lower spark plug than Champion OE for 3.8L Wrangler
Used NGK LZTR5A-13, no one in Melbourne had a lower heat range Platinium plug in stock so used a Nickel plug, will only be good for max 10Ks
Hooking up van next week and see how it goes
