Frequently Asked Questions About International S2200-S2600 Engine Performance Parts

Will these performance parts fit my specific International truck model and year?

Our S2200-S2600 engine performance parts are designed to fit International trucks equipped with MaxxForce 11 and 13 engines, typically found in ProStar, LoneStar, PayStar, and 9900i models from 2010-2015. However, compatibility can vary based on your specific engine configuration and emissions equipment. We recommend checking your engine serial number or calling our tech support at 1-888-875-7787 with your VIN to confirm fitment before ordering.

What kind of power gains can I expect from these performance upgrades?

Performance gains vary depending on the specific parts and combinations you choose. Typical improvements include 15-25% increases in horsepower and 20-30% gains in torque with ECM tuning. Air intake upgrades can add 5-10 HP, while exhaust modifications may contribute another 10-15 HP. Turbo upgrades can provide the most significant gains, often 50-100+ HP when combined with proper tuning. Keep in mind that actual results depend on your engine's current condition and other installed modifications.

Are these parts legal for on-highway use, and will they affect my warranty?

Most performance parts in this category are designed for off-road, competition, or testing purposes only and may not be legal for on-highway use in all states. ECM tuning and exhaust modifications that remove or bypass emissions equipment will void your engine warranty and are not DOT compliant. Some parts like air filters and certain exhaust components are 50-state legal. Always check your local and state regulations before installing performance modifications.

How difficult is the installation, and what tools will I need?

Installation difficulty varies by product. Air filters and simple bolt-on parts can typically be installed in 30-60 minutes with basic hand tools. Exhaust systems usually require 2-4 hours and may need cutting or welding. Turbo upgrades and ECM tuning should be performed by experienced diesel technicians and can take 4-8 hours. Most installations require standard metric wrenches, sockets, and potentially specialized tools like torque wrenches or diagnostic equipment for ECM work.

Will these performance parts affect my fuel economy?

The impact on fuel economy depends on the parts installed and your driving habits. Properly tuned ECM modifications can actually improve fuel economy by 1-3 MPG under normal driving conditions through optimized fuel mapping. High-flow air filters and exhaust systems may provide slight improvements of 0.5-1 MPG. However, if you use the extra power frequently for heavy hauling or aggressive driving, you may see decreased fuel economy. Most customers report break-even or slightly improved MPG with conservative driving.
