I'm sure there's a cheaper alternative out there, but even if not, really? $50 is too much to spend on your car for plugs that will last 2+ years? Preventative maintenance means the car will run better and last longer. News flash, cars require preventative maintenance.

as a Ford tech, i see all kinds of el cheapo plugs that don't work properly in Fords almost on a daily basis. the most common blown out spark plugs from the 4.6l and 5.4l engines are Champion, bosch, autolite. these plugs will also make the engines misfire at highway speeds. the 5.4 3valve engine takes a special plug that runs about 17 each bucks at dealer. around 11 bucks from Orielly auto parts that carries Motorcraft. guys i understand parts being expensive, but this is one area that i would high recommend using what was designed for from the manufacturer.

Lol I love the RX7's but rotaries make me uneasy ever since my last one, My car was running very well before I went on vacation, I drove around all day the day before I left cruising around town and just driving pretty easy no beating on the car...I parked it and went on vacation for 2 weeks and when I came back I went to crank the car up and I hear CLANK and that was it the motor was done and had to be rebuilt which REALLY pissed me off as it was out of nowhere I ended up just selling the car instead of getting a new motor for it since I was thinking about selling it anyways before the motor went |

Spark plugs for a G3500 and G3600 Cat engines run about $100 apiece. Some of our customers try and skimp by with cheap as champions and it never fails that we will be back out there changing a plug here and there before the next pm. Use what the manufacturer recomends, it can save alot of headaches.

Thank God for Time-Sert, Took me better part of a day to DIY but way cheaper than the $800-$3000 I was quoted by the dealer. New OEM coil & new MC plugs. Even with the Time-Sert kit, which I found a deal on on Ebay, the repair was less than $300 and I can probably get $250 of that back selling the repair kit back on Ebay. |
