Opti injectors are around $300, it takes 12 for a V6, 6 fuel, and 6 air(yes, they go bad also), they can be cleaned for around $80 each. Fuel pressure regulators on the fuel rail are not servaceable, they include the fuel rail(around $1300). The platinum plugs are $29 each, plus you can put over $100 of filters(air and fuel) at your next tune up. Now throw HPDI's in the ring, high pressure fuel pumps are over $1000, I can't find any one to clean(and guarantee) HPDI injectors, Injectors are over $300 each(only 6 to mess with). Electric fuel pumps are over $600(fourstroke also), the high pressure fuel filter was over $300, dealers complained about it so much they dropped the price to around $120(?, I haven't had to replace one lately), still pretty high. Add in DFI oil($35-$45a gal), adn ring free or carbon guard(highly recomended) at $20 per 100 gal. These things get real expensive,real quick. They can save you a lot on fuel, but they will eat you alive on other issues. I looked at a 115 Yamaha 4 stroke the other day, it wouldn't shut off, you could unplug the harness and it would keep running, you could lightly tap the computer and it would shut off, guess what, $1300 for the computer. lately, teh most expensive things I've been seeing is trim systems, just worked on a Johnzuki, had over $850 in parts on the trim system( '03 140 fourstroke), put a trim motor on a 225 yamaha, $580 for the motor. Makes me like the old 2 strokes better and better, Of course, these new motors are what keeps me in business
