Product Details

The Hedman Hedders 21107 is an oxygen sensor reducer bushing designed for custom exhaust header installations. This precision-machined adapter allows you to properly install an O2 sensor into an exhaust header bung that has a different thread size than your sensor.

Key Features:

  • Allows proper oxygen sensor installation in mismatched bung sizes
  • Precision-threaded steel construction for reliable sealing
  • Heat-resistant design for exhaust system durability
  • Essential for custom header installations and sensor replacements
  • Ensures proper sensor positioning for accurate readings

This reducer bushing is ideal for enthusiasts building custom exhaust systems or replacing oxygen sensors where the factory bung size doesn't match the sensor thread pitch. Proper installation ensures accurate oxygen sensor readings and prevents exhaust leaks at the sensor port.

Easy, cheap, reasonable shipping

Not only was it the cheapest price, but they had the fastest and lowest price shipping, and best customer service. Thanks Autoplicity!

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

Great prices and fast shipping! What more could you ask for?

Great prices, fast shipping.

Good service, fast shipping, excellent prices
