RENNtech SPEEDSHIFT Valve Body Upgrade w/ Throttle “Blip”

Thursday, April 24th, 2014

The staple of advanced or professional driving is the “rev match”, or “throttle blip”, in which the driver quickly brings the engine up to speed with the wheels by use of the throttle. This was not possible with the automatic transmission in the CLK Black Series…until now.

RENNtech is proud to offer our Speedshift performance valve body upgrade for the CLK black series. Our upgrade modifies the shifting performance characteristics of the transmission control unit, the transmission valve body and allows the vehicle to automatically “blip” the accelerator upon down shifts allowing for quicker gear engagement and faster lap times.

When downshifting, the engine throttle is increased to allow the engine to match the RPM of the lower gear and allows for significantly faster gear engagement . When coupled with our transmission upgrade, this is the ultimate upgrade for your CLK Black series.

Performance Spark Plug Upgrade for Biturbo Engines (M157 & M278) Available Now!

Friday, April 5th, 2013

The RENNtech performance spark plug upgrade utilizes high quality NGK spark plugs in a cooler heat range than the OEM Bosch plugs.

With the increased performance and boost pressure generated from performance tuning comes increased combustion temperatures. With OEM plugs, this additional cylinder pressure can cause pre-ignition and premature spark plug fouling.

Our performance spark plug package uses a “colder” heat range plug which allows spark plugs to fully ignite the mixture and allow the engine to maintain higher boost levels across an extended RPM range.

This plug upgrade also improves idle quality and is the perfect replacement for vehicles experiencing spark plug or rough idle issues.

  • Kit comes with 8 spark plugs
