Bought these sp's and installed myself. Gapping for fj should be 0.38-0.43. These come at 0.44. I didn't make an adjustment. Installed watching a Youtube video. Took about 2 hours. Make sure you purchase a 3/8 inch ratchet with a torque measurement ($40) in/lb, 3/8 - 1/4" ratchet convertor, spark plug bit with magnetic bit (must) and correct lube.
After installation, turned off all dash lights. Car now runs at fj standard 550 rpm (was at 1000 rpm). Saved a ton of cash doing this myself. The sp's were brownish at the ends when I took them out. I will now swap out every 30k (recommended). Should only take an hour now.
Would buy this product again (and will for my Subaru STi).
