RCM Tumbler Generator Valve (TGV) Thermal Delete Kit

SEN1386 (red)

Tumbler Generator Valves (or "TGV" as they are most commonly referred to) can be found on Impreza WRX, Forester Turbo and Legacy GT models from 2001 onward.

Their prime purpose is to reduce emissions from cold idle to meet standards governed by the EU emissions regulations (similar regulations also exist for both the US and Japan). Whilst this may be good for the environment it does little to aid the performance of your car and it's not uncommon for the sensors and motors connected to the TGV body to fail (leading to "limp mode", CEL lights and ultimately considerable expense in replacement parts and code clearing).

The standard TGV's are similar to the design of your throttle body, encompassing twin "butterfly" valves in each tumbler housing to control air flow. Even when fully open these restrict the flow of air traveling into the cylinder head ports, reducing performance. This coupled with the possibility of sensor and motor failure mean there is good call for an improved alternative!

RCM TGV Delete's do not contain any butterfly valves, sensors or motors and allow for a smooth, direct flow of air into the cylinder heads. Whilst it is necessary to initially adjust the ECU mapping to prevent a check engine light the results offer; increased performance, improved reliability and a much improved esthetic appearance (thanks to our crinkle red coated finish).

Our "Thermal Kit" also has the added features of heat spacers included.These will help prevent heat from conducting into the alloy inlet manifold from the cylinder head, as a result the cooler and denser air will aid performance and keep temperatures stable under prolonged engine running. Due to the increase in manifold height when installing thermal spacers we also supply a replacement bolt kit, this ensures the OE thread depth into the cylinder heads is maintained and the manifold and TGV housing are kept secure on your engine. Also included are all necessary manifold gaskets offering a trouble free installation. 

# technical specification

• X2 Aluminium tumbler castings, finished in a choice of crinkle red or black powdercoat.

• X2 Inlet manifold to tumbler casting gaskets.

• X2 Tumbler to Thermal Spacer gaskets.

• X2 Thermal Spacer to Cylinder Head gaskets.

• X1 Bolt Kit to secure the manifold and tumbler castings to the cylinder heads.

• NOTE - For Impreza WRX and Forester models CEL light removal is necessary by aid of ECU adjustment from your nearest ECU Mapper.

# key features

• Removes existing TGV deletes containing butterfly valves, sensors and motors.

• Provides improved airflow from the inlet manifold through to the cylinder heads.

• Improved heat management by reducing temperature transfer between the inlet manifold and the cylinder heads.

• Removes potential future failures with both the TGV position sensors and Motors.

• Improves engine bay appearance thanks to the crinkle red or black paint finish.

• Increased engine performance.

# confirmed applications

• Impreza WRX 2001-2007 (ECU Remap required after fitting).
• Forester XT, XTN, 2003-2007.

RCM TGV delete kit can also be used on STI / WRX 2008+ however modification is required to the centre bolt holes on the TGV castings. Prior mechanical knowledge and specialist tools are required. Please contact us for more details prior to purchase.
