Lambda-ECO oxygen sensor with genuine BOSCH head warrants dramatic increase of MPG by an average of 15% without compromise with engine performance. Gas mileage boost is over 12% on highways. You don't lose horsepower at the wheels or have to drive slowly & thriftily. The state-of-the-art λ-ECO oxygen sensor is an affordable economizer gives you the mileage boost you are looking for! It replaces factory post oxygen sensor and available to all vehicles controlled with narrowband 1 up to 4-wire zirconia type oxygen sensor originally. λ-ECO O2 sensor will not affect engine reliability & durability and pays for itself in no time at all. It does not work in conjunction with some upgrades as decats, catbacks, performance chips, etc. Lambda-ECO is maximizing the Air Fuel Ratio indicating fuel rich status in those circumstances when oxygen sensor is sensing idle speed, low/medium engine load or while driving is nearly constant without severe accelerations. When throttling suddenly, so acceleration is essential, unit returns to factory mode with no delay & engine is actuated promptly because oxygen sensor will deliver the ECU factory signals until acceleration keeps on. Tests on fuel economy have given an increase of 3-7 MPG depending on engine size, terrains, tire size etc. Magnum Tuning has been applied the latest test-proven techniques and innovative designs since 1994 to improve upon fuel efficiency.
