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.

Do you offer wholesale or jobber pricing?

Yes. Wholesale pricing is available for legitimate businesses that provide a valid business number or equivalent proof. Ongoing purchase volume is required to maintain discount eligibility. One-time personal buyers aren’t eligible.

Will this part fit my vehicle?

If a product page clearly lists fitment for your vehicle and the description leaves no reasonable doubt, we’ll cover the cost of return if it doesn’t fit. Exclusions apply if prior modifications cause the issue. When browsing self-serve, you’re responsible for confirming compatibility by checking manufacturer fitment data and notes. If unsure, contact us before ordering and we’ll verify it for you.

Do you offer technical support or installation advice?

We help where possible on a case-by-case basis. Most manufacturers include detailed instructions and tech support contacts. Because our catalog spans hundreds of brands, we can’t provide every torque spec or procedure, but we’ll connect you with the manufacturer if needed.

Do you offer price matching?

We don’t guarantee price matching, but we’re happy to review a legitimate in-stock offer from another Canadian retailer. The comparison must include all costs such as product price, shipping, taxes, and fees, and the item must be identical and available for immediate purchase. We won’t lose money to match unsustainable or out-of-stock pricing.

Can I exchange an item?

Yes. In-store exchanges happen on the spot when stock is available. For shipped orders, the original item must be returned first. Once received and inspected, we can issue a store credit toward the correct part or replacement. We can’t send a second item while the first is still in your possession without payment for both.

Are prices shown before or after tax?

All prices on the site are before tax. GST, HST, or PST is calculated at checkout based on your shipping address..
