<p><b>Note: Please check fitment and description for accurate information！！！</b><br/> <br/> <b>Made to Meet or Exceed Original Equipment Standards</b><br/> KAX premium oxygen sensors are manufactured to exacting standards,utilizing the most up-to-date<br/> production technology to bring you an O2 sensor that keeps your engine running at its best, for longer.<br/> <br/> <b>KAX 234-4668 oxygen sensors feature:</b><br/> - Double laser-welded body for durability<br/> - Fast-acting heater for optimal sensor operation<br/> - Premium sensor tube for 100% accurate data<br/> - Coated threads for easy installation<br/> - 440mm cable<br/> <br/> <b>Timely Replacement of Your Vehicle’s Oxygen sensors Matter!</b><br/> <br/> <b> Why Choose KAX Oxygen sensors?</b><br/> <br/> <b>Improved engine performance</b><br/> A correctly operating oxygen sensor ensures efficient engine operation<br/> by making sure the engine is receiving the correct air/fuel mixture and thereby preventing the engine running lean or rich.<br/> <br/> <b>Increased fuel efficiency</b><br/> The sensor achieves optimal engine performance by monitoring the <br/> oxygen content in a vehicle’s exhaust and regulating the air/fuel mixture to the ideal ratio of 14.7 parts air to 1 part fuel.<br/> <br/> <b>Lower emissions</b><br/> If the optimum fuel mixture is not maintained, the engine can emit<br/> harmful amounts of carbon monoxide and excessive levels of hydrocarbons.<br/> <br/> <b>Prevents catalytic converter damage</b><br/> As the catalytic converter is responsible for eliminating harmful gasses<br/> from the vehicle’s exhaust system, an incorrectly operating oxygen sensor can cause premature damage to your catalytic converter.</p>
