The JRP LSU 4.9 wideband oxygen sensor is a high-quality, cost-effective replacement for Bosch 4.9 sensors. Designed for use with our Spartan wideband controllers, but also with other wideband controllers that utilize the 4.9 sensor technology. These sensors are also an excellent choice for dyno workshops where durability, reliability, and value are crucial.
Dyno environments are notoriously harsh on O₂ sensors, treating them as consumable items due to constant wear. By offering a sensor equivalent in performance and durability to Bosch’s 4.9 at a lower price, JRP provides workshops with significant cost savings without compromising accuracy or longevity. Bulk purchasing options further enhance the value for high-usage applications.
Why Choose JRP LSU 4.9 Sensors?
Since our inception, JRP has specialized in precision sensor technology. Our multi-gauge systems depend on sensors that deliver accurate, reliable, and durable readings, so we’ve invested years of expertise into developing a product that meets those standards.
- Rigorous Testing: The JRP 4.9 sensor has undergone extensive lab and real-world testing. Lab gas tests performed by 14Point7 confirmed accuracy on par with Bosch sensors. Dyno shop trials demonstrated equivalent durability and performance under harsh conditions. Long-term road tests in daily-driven performance vehicles further validated their reliability.
- Proven Performance: From high-end dyno widebands to everyday performance applications, our sensors match the accuracy and lifespan of Bosch’s 4.9 sensors.
- Cost Savings: Offered at a lower price point, these sensors help reduce annual expenditure for workshops and individuals alike.
Versatile Compatibility
The JRP LSU 4.9 sensor is compatible with a wide range of wideband systems, including those from AEM, Innovate, PLX, Haltech, Link, and more—any system utilizing the 4.9 standard. For our Spartan wideband kits, these sensors now come as standard, ensuring a high-quality, budget-friendly solution for our customers.
Built on Experience
The JRP 4.9 sensor project began nearly three years ago during the development of 14Point7’s Spartan 3 range. Through meticulous R&D and collaborative testing with industry experts, we’ve created a sensor that meets the high standards of the Bosch 4.9 while offering a more affordable option.
If you are operating a dyno and managing a performance workshop, or need a reliable replacement for your personal wideband controller, the JRP LSU 4.9 wideband 02 sensor delivers exceptional performance, proven durability, and outstanding value. And when it’s time for a replacement, rest assured you’ll find the same quality and cost savings every time.
JRP stands behind every product we produce, and the JRP LSU 4.9 wideband sensor is no exception. If it didn’t meet our exacting standards, it wouldn’t be here.
