The BoosterPlug is an effective and cost efficient way to cure the fuelling problems common to all modern fuel injected Guzzi's.
Plugging directly into the wiring harness using original connectors, with no cutting or splicing required, installation takes less than ten minutes.

The BoosterPlug features a unique technology to provide your bike with a controlled fuel enrichment in all ambient temperature situations. No other Plug and Play device does this. A richer mixture is provided only when needed i.e at low RPMs and when accelerating. On open roads at a constant speed the Boosterplug sits idle to keep fuel consumption low.
Make your bike run as it should have done from the factory!

• Improved and gentler throttle action when opening and closing throttle
• Richer mixture when opening the throttle improves acceleration
• Booster plug removes the uneven low speed running that is typical for modern lean burn engines
• Stronger and more consistent at idle.
• Reduced backfiring with aftermarket exhausts on engine braking
• Improved fuel economy

HIgh performance aluminium velocity stack for airbox to throttle body union. This velocity stack replaces the standard part with an aluminium part that protrudes into the airbox. Through careful design it improves the engine response by providing an increased volume of less turbulent air to the throttle body. No modifications are required to fit this velocity stack but you should see a torque increase of around 6% at 2500 RPM and 3% increase in power at 6500 RPM

This manifold is suitable for EURO 4 and 5 models, manufactured on the shores of Lake Como. Developed for optimum power and torque on Mistral's rolling road. For best results combine with a performance air filter - SIA10433 and V-Twin Boost - ACA85001 or ACA85002.

Customer Kev fitted this combo and called us the next day to say that his V85TT was transformed; the fluffy throttle response between 2k and 3k was gone and the engine pulled better. Simple to fit, installation time is less than 30 minutes and the battery does not need to be disconnected.
