How do you guys with the 3.68's like them so far? I've seen both great and terrible reviews out there. PROBABLY because people were using the wrong short plugs...

I installed the 3.68's a couple months ago (June 15th) at 18,500 miles. Since theh, I drove to the Summit (1900 miles round trip), but other wise commute driving. I now have 21,500 on the vehicle and I have noticed a slight improvement in mpg (about 0.3-0.5 mpg) and the FJ seems to start easier.

If it's time to change the plugs in your FJ, the E3.68 will not disappoint you. IMHO. I purchased the plugs on-line from Amazon dot com.
