The cost to change spark plugs on a 2003 Mitsubishi Montero Sport typically ranges from $100 to $300, depending on labor rates and whether you choose to use OEM or aftermarket spark plugs. Labor can account for a significant portion of the cost, especially if the spark plugs are difficult to access. Additionally, if other maintenance or repairs are needed during the process, that could increase the total expense. Always check with a trusted mechanic for an accurate estimate.

We have a 1995 Mitsubishi Montero (the people that brought your the fighter ZERO) and when it came time for a tune-up we couldn't get the plugs out. The car dealer here charged us over 500 dollars for a tune up and they had to remove the top part of the engine to reach the plugs, hence the large dollar value. We will NEVER own another Mitsubishi again! Good luck:)
