X8R Ltd is a British company completely dedicated to providing high quality improved design vehicle components; correcting original manufacturers design faults. We take the common faults associated with a variety of vehicle manufacturer’s parts and re-design and manufacture parts that will not fail again or that will prevent damage to vehicles.
Vehicle idles poorly, rough, high or low idling and stalling. Vehicle in limp home mode or reduced power warning or EPC light on / lit. Revs not dropping back down after accelerating. Throttle delay. Poor MPG
The throttle body is integral to the air intake system and controls the amount of air flowing into the engine.
The butterfly valve within his mechanism often becomes coated in carbon deposits. This can affect the valves opening / closing or jam open / shut causing vehicle faults.
Often this is cleaned to restore function. If this doesn’t resolve the fault the throttle body is replaced. This is rarely necessary.
Often the build up of deposits has stripped the poor-quality Nylon gears within the mechanism stopping correct function.
These gears can easily be replaced with our improved material gears resolving vehicle faults without having to replace the complete throttle body which would only fail again.
Install our replacement gears and restore full function of the throttle body.
Our gears are unique in design they can simply be push fitted and can be installed very quickly please check out our instructions guide.
Our gears work in exactly the same way as the OEM components but are constructed from a far superior material, a Carbon reinforced plastic, specifically formulated for this application.
Our gears are injection moulded high quality parts, be wary of 3D printed and metal gears which can cause further issues.
We also include a replacement seal for the actuator housing which is opened to replace the gears.
A full-term solution to this very common fault.
