Performance parts package 1.8 NA SG140

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 the SPS header kit for self-installation. Ignition adjustment, dyno run, and TÜV registration are not included.
• Full Installation (with tuning & registration): The kit is professionally installed at SPS Motorsport. The ignition is set to 14° BTDC, followed by a dyno run on our in-house test bench — including a performance 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
• Ignition adjustment via timing light
• Dyno run incl. performance protocol
• TÜV registration at SPS Motorsport

Power Increase – Up to 140 HP

This setup delivers a noticeable increase in throttle response, torque, and sound. The SPS header improves exhaust flow and overall engine efficiency — 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!
