Mazda RX-8 Power Parts For Sale

Bundle your intake upgrades into one kit for better flow, cooler charge air, and crisper throttle response, simplifying the path to a stronger, more responsive engine.

Swap the restrictive manifold for a tubular stainless header that improves exhaust scavenging, sound quality, and top-end power potential.

Replace the rear silencer with a freer-flowing tail section that improves tone, reduces restriction, and maintains comfortable cruising manners.

Upgrade to a performance cat-back system that delivers a deeper tone, smoother flow, and improved top-end power while remaining civilised for daily use.

Improve cold starts and reliability with a higher-torque starter motor that cranks faster, reducing stress on the battery and making life easier in cold weather.

Upgrade the charging system with a high-output alternator in a bold finish that supports heavy electrical loads and keeps voltage stable under all conditions.

Sharpen throttle response with an in-line accelerator controller that offers multiple modes for city, sport, and track driving without changing the ECU tune.

Reduce rotational mass with a lightweight flywheel that helps the engine rev faster, improving throttle response and making heel-and-toe work more satisfying.

Upgrade to low-resistance leads that deliver stronger spark, reduce misfires, and help maintain reliable combustion under load and at higher RPM.

Reduce parasitic loss with a lightweight pulley set that helps the engine rev more freely and complements other breathing upgrades.

Increase charging capacity with a high-output alternator that supports additional gauges, lighting, audio, and engine management without sagging voltage.

Upgrade the intake plumbing with a smoother, freer-flowing suction kit that helps the engine breathe, improving throttle response and induction character.

Upgrade the entire intake path with a matched system that improves breathing, response, and induction sound while working with factory sensors.

Replace ageing ignition coils with a complete matched set to cure misfires, improve cold starting, and support reliable performance at higher RPM.

Restore engine performance with a complete factory short block, ideal for reviving tired, low-compression or damaged units.

Rebuild a later-series car with a fresh short block that offers factory reliability and a clean starting point for future modifications.

Renew the ignition system with fresh plugs matched to rotary use, improving starting, idle quality, and combustion stability under load.

Swap out the stock panel element for a high-flow performance filter that improves breathing, enhances response, and is designed to work within the factory airbox.

Free up exhaust flow with a high-flow metal catalytic converter that reduces backpressure, sharpens throttle response, and supports future tuning without harsh drone.

Replace the restrictive factory intake tube with a smooth, larger-diameter pipe that reduces turbulence, improves airflow, and supports future power modifications.
