I believe I read in the manual around 60k. I just changed them on my "new" '05, and they were really bad, possibly the originals. 114k miles.
Went with Champion coppers.

Every 30,000 sometimes a little sooner
, Champions copper core

Still got my plugs from the factory. My KJ just rolled over on to 51K. Still getting an avg of 16-18 MPG in city.

Only changed mine once in 55 years. :mexsmoke:

Did not vote since my option is no listed.I change mine once a year regardless of mileage,copper core champions.

25-30k with NGK coppers. Used the platinum Bosch +4s one time and didn't idle nearly as well as with the coppers.

25-30k with ngk part number listed on emissions sticker

jeepguy4276 · Mar 21, 2015

I change once a year with the ngk' listed on emissions sticker.

rcjohnson · Mar 21, 2015

I changed them with NGK's but I plead the 5th on how many miles were on it when I did change them.

Leeann · Mar 21, 2015

NGK copper. Will be done every 25-30k miles from now on. I'm not sure I didn't replace the originals at 79,000 when I took possession.

25-30,000 miles using NGK copper core. (OEM ones)

^Please post the gap size and photos when you do remove them! (hopefully real soon!)

CalcityRenegade · Mar 23, 2015

Once a year with Champion Copper's however this year I went with the OE NGK's because I could not find the Champions, Nobody had them in stock.

colorado76 · Mar 23, 2015

I change my spark plugs once a year in the fall, regardless of mileage. I use NGK's or Champion's copper cores. I also have ran Champion Platinums but copper runs the best. :ryu-cvs-hadoken-a:

Done. But I threw them out and didn't take pictures (sorry). Gap size was about .075. Surprised it was running as well as it was. I notice absolutely no difference in power. Maybe I'll see a bit in MPG.

After 20 miles I put in NGK Cops. (ok... i just bought her used with 129k on it) I thot I'd be pulling out the original plugs but was surprised to see Denso plugs in there. I'll probably keep to a 45k routine though.
