I18n Error: Missing interpolation value "end_date" for "Ends on {{ end_date }}"

The Bosch LSU4.2 and LSU4.9 wide-band O2 sensors (shipped standard with Innovate Motorsport products) are rated to operate at an exhaust gas temperature of < 1,700 Fahrenheit (930 Celsius), and a sensor housing temperature of < 1,058 Fahrenheit (570 Celsius) measured at the hex, for maximum accuracy and control. When either of these operating temperature ranges is exceeded, the sensor can no longer be accurately controlled. Further, operating at or above these temperatures for any length of time can significantly reduce the life expectancy of the sensor. Innovate Motorsports products are designed to display an error message under these conditions (08- Sensor Timing Error) rather than provide inaccurate readings. For some turbo vehicles, rotary engines, and other specialty setups, this error message can be encountered with annoying frequency due to operating conditions specific to those engine types and configurations. This precision machined part is engineered to address applications generating excessive heat in the O2 sensor by utilizing a specialty heat sink design which pulls the sensor futher out of the exhaust stream while maintaining correct flow of exhaust gasses to the sensor for accurate readings.

  • Specialized heat-sink design pulls sensor 1.1875" (30mm) out of original weld boss, reducing applied temperature to the sensor while maintaining critical flow of exhaust gasses to the sensing element for accurate readings.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.


    Donald Wojnar
  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.


    Adam Cranston
  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.


    Bryce Budd
  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.


    William Brunell
  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
