Performance parts package 1.8 NA SG152

This performance package was developed by SPS Motorsport on the racetrack, adapted for street use, and continuously refined. All components are engineered in-house and used in our own race cars — delivering maximum efficiency, uncompromising quality, and a clean, OEM-like engine bay appearance.

Two Options – Parts Package or Full Installation

You can choose between two configurations:

• Parts Package (without installation): You receive all components for self-installation. ECU tuning, dyno protocol, and TÜV registration are not included.
• Full Installation (with tuning & registration): All components are professionally installed at SPS Motorsport. The ECU is then individually calibrated on our in-house dyno and on the road — including dyno protocol. Finally, the entire conversion is inspected and officially registered at our facility. Registration is included in the price.

Included services with full installation:

• Installation of the SPS header kit
• Installation of the standalone ECU incl. wideband lambda sensor
• ECU calibration on dyno and road
• Dyno run incl. performance protocol
• TÜV registration at SPS Motorsport

Power Increase – Up to 152 HP

This setup delivers a significant increase in throttle response, torque, and top-end power. The combination of SPS header and standalone ECU unlocks the full potential of the naturally aspirated 1.8 engine — ideal for spirited street driving and track use.

Exhaust System Requirement

⚠️ Full power is only achieved when paired with an exhaust system featuring a minimum pipe diameter of 55 mm. We recommend our Group A exhaust system, which can be added as an accessory during checkout. Without it, the full performance potential will not be reached.

Registration & Certification

⚠️ This performance package can be combined with these exhaust systems:

• Friedrich Motorsport Group A
• IL Motorsport
• BBK
• Don Silencioso
• Fox/SPS Group A
• Fox/SPS JDM

For other exhaust systems please contact us in advance via email, so we can check first whether a TÜV registration is possible.

Developed with Motorsport DNA

All performance packages are configured in-house at SPS Motorsport. Whether you're aiming for lightweight NA tuning, ITB conversion, or turbocharging – we use all components ourselves and put them to the test on the racetrack. Our development focuses on harmonious power delivery, maximum reliability, and a clean, OEM-like engine bay appearance.

Upgradeable & Modular

Our performance packages are modular and fully upgradeable. If you decide to expand your setup later, we’ll provide the right support and advise you on meaningful upgrades.

Lifetime Support

Every performance package installed by us comes with lifetime support. Since we use these products ourselves — on the road and on track — we can help with nearly any issue quickly and practically. Got questions? Just ask!
