Sweet Ride
By Robboman48 on
Vehicle
2003 Mitsubishi Diamante ES 4dr Sedan (3.5L 6cyl 4A)
Review
Purchased with 79k miles for $7k. Same yr Avalon $15k. Added Bosch Platinum 4 plugs and it changed this car immediately. Has plenty of go, we now average 27 mph hwy on regular gas and Valvoline hi-mileage synthetic oil. Never a problem, looks and positive comments from others. Very comfy on a + 6hr ride in front and back. Leather is sweet and sound system is great. Best buy for the money.
Favorite Features
It has a sweet little exhaust rumble that gets attention on acceleration but goes silent at hwy speeds.
Suggested Improvements
I would advise anyone to add the Bosch Platinum 4 plugs. It definitely increases gas mileage and the performance can be felt. Had NGK Platinums originally. Installed plugs myself with front 3 easy, back three take time since you have to remove the fuel manifold. No hard, time consuming.
