AMS Performance: Aftermarket Performance Parts for Import Vehicles
AMS Performance is a Chicago-based manufacturer and retailer of high-performance aftermarket parts for import vehicles, with particular specialization in Mitsubishi Evo, Subaru WRX/STI, Nissan GT-R, and other turbocharged performance platforms. The company is known for record-setting builds and engineering-first approach to performance parts development.
AMS Performance's Engineering and Testing Methodology
AMS differentiates from catalog resellers through in-house design, testing, and manufacturing of performance components. Using a dyno facility and track-tested platforms, AMS validates performance claims with objective power measurements rather than marketing projections. This engineering rigor has produced multiple world records on platforms including the Nissan GT-R, establishing the brand's credibility in the high-performance community.
Key Performance Categories AMS Serves
AMS Performance produces and sells intercoolers (larger core units that reduce charge air temperature for more power and efficiency), turbos and turbo kits (larger turbines for more airflow and boost), intake manifolds, downpipes and exhaust systems, air-to-water and air-to-air intercooler systems, and complete engine build components for race-level builds. Each category targets specific power and reliability goals.
Intercooler Upgrades: Why They Matter for Turbocharged Performance
Factory intercoolers are sized for stock boost and power levels. As boost pressure increases through ECU tuning, the stock intercooler becomes a thermal bottleneck -- excessive charge air temperatures ('heat soak') reduce power and risk engine damage through detonation. AMS's larger-core intercoolers maintain lower charge air temperatures under sustained boost, allowing safe increases in power that the factory intercooler cannot support.
ECU Tuning: The Foundation of Modified Performance
Aftermarket parts deliver full potential only with supporting ECU (engine control unit) calibration. Adding a large intercooler and upgraded fuel injectors without updating the fuel and ignition maps to match can result in lean conditions that damage engines. AMS builds are typically accompanied by professional ECU tuning -- either through mail-in ECU service or on a dyno facility -- that optimizes all engine parameters for the installed parts combination.
Reliability and Street Usability Considerations
High-power modified vehicles present reliability trade-offs. Power levels above ~400whp on most stock internal components create risk of transmission, drivetrain, and engine failures not seen at stock power levels. AMS and comparable performance shops offer full engine builds with forged internals when targeting power levels that exceed stock component limits. Understanding these thresholds before modifying prevents premature mechanical failures.
Using SaveSpire for Performance Parts Discounts
SaveSpire maintains promotional codes for automotive performance parts retailers. Before ordering AMS Performance parts or competing performance components, checking SaveSpire for available discount codes can reduce cost on what are typically premium-priced performance investments. Performance parts sales at specialty retailers periodically offer meaningful discounts on brand-name components.
Q: What power levels can a built GT-R reach with AMS components?
AMS Performance has built GT-Rs producing over 2,000 wheel horsepower on their Alpha 20+ platform -- among the highest-powered GT-R builds in the world. Street-oriented builds on the GT-R platform using AMS components commonly achieve 800-1,200whp with appropriate engine and drivetrain preparation. Real-world street reliability at these power levels requires comprehensive preparation beyond engine output alone.
Q: Does AMS Performance offer phone or email consultation for build planning?
AMS Performance and similar specialty performance shops typically offer technical consultation for customers planning builds -- either by phone, email, or in-person at their Chicago facility. Consulting with AMS technicians before ordering parts ensures component compatibility and appropriate parts selection for your power goals and intended use (street, track, drag racing)
