Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 200698 neon plug lifespan
co-worker's car. a set of plugs is lasting him about 3 months. this time he changed the plugs and wires. gapped to about .035" The plugs he took out were totally worn again, this was the second set in 6 months that's gone in at 035 and come out around 050. Are neons this hard on plugs? Ray > co-worker's car. > a set of plugs is lasting him about 3 months.

My Brother in-law was recently bitching that his '99 F-150 needed plugs again after only 20k miles and a years time. He put the cheapest he could find Champions in it last time. I recall him saying that the OEM plugs would have cost $80. Now he gets to pull the fuel rail and futz with the coil-on-plug PITA that the Ford Triton V-8's are, again. Not much savings IMO. The iridium/platinum or whatever other "special" coating is on modern plugs keeps the electrodes from eroding with todays super hot ignition systems. Plain 'ol copper plugs won't last long even if they physically fit. >> co-worker's car. >> a set of plugs is lasting him about 3 months. [quoted text clipped - 22 lines] > systems.

Should a 98 Neon be using platinums? Am open to suggestions as to what kind to recommend for him if he needs to do it again in three months. (Like I said, he did the wires this time too and I lent him my autotap to scan his car...) Ray >>> co-worker's car. >>> a set of plugs is lasting him about 3 months. [quoted text clipped - 32 lines] > > Ray I dunno as I have no specific experience with a 98 Neon. I have learned through various tuneups of late model vehicles that you have to be *VERY* careful to put OEM quality plugs in them. Close enough or "just slightly" different often doesn't work out well. I recently had to pull nearly new Champions out of my Father-in-Law's 2001 Buick due to it setting a random misfire code 600 miles after he put the Champions in as "preventive maintenance" (no MIL on or other trouble before this). I replaced them with AC's ($55!) and cleared the code. All is well 1000 miles later... >>>> co-worker's car. >>>> a set of plugs is lasting him about 3 months.

I replaced the platinum plugs in my 01 Trans Am with regular old champions or AC's when I installed nitrous. Car has never set a misfire code. but my buddy's PT Cruiser had the plugs replaced under warranty for the same reason... Ray |
