Featuring a fast-acting heater and a durable stainless steel body, it ensures rapid sensor activation and long-lasting performance. Factory-tested to meet Bosch’s rigorous quality standards, this sensor optimizes engine efficiency, reduces emissions, and simplifies installation with OE connectors and anti-seize coated threads. ## Description Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production since the first Oxygen Sensor was invented in the late 1960's, ensuring long-lasting performance that you can count on. Bosch Oxygen Sensors are 100% tested for full functionality to ensure every sensor meets Bosch's rigorous standards for quality and performance. Stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions - ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors, allowing the oxygen sensor to reach its operating temperature quicker - within seconds - for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It's critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers - before the sensor fails. Following the recommendations will prevent long term damage to a vehicle's engine, reduce harmful carbon dioxide (CO2) emissions, and save you money when filling up at the gas pump. Review: Still Working - Was proactive on replacing this part, gas mileage improved, 30 up to 40 miles per gallon, 2.2L 99 Outback Sport Wagon, Impreza, normally aspirated. Speeds up to 80 mph, altitudes up to 10,000 feet. Would do business again with this vendor. Price more than competitive. Delivered to front door.

Speeds up to 80 mph, altitudes up to 10,000 feet. Would do business again with this vendor. Price more than competitive. Delivered to front door. ### ⭐⭐⭐⭐⭐ Need a split socket *by S***S on June 24, 2023* Plug together to use ### ⭐ NOT an exact fit as advertised *by J***Y on December 4, 2009* The sensor itself fits of course, but the connector doesn't fit even with modification. Had to splice in the old connector which was extremely tedious and voids the entire reason for purchasing an EXACT FIT sensor. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/143580517-bosch-15638-premium-oe-fitment-oxygen-sensor-compatible-with-select](https://www.desertcart.dk/products/143580517-bosch-15638-premium-oe-fitment-oxygen-sensor-compatible-with-select) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-06-21*
