If you know us, you know we do harnesses. Quality Harnesses. These come in 12" and 24" extensions for the Gen III/IV Hemi. These can be used in Modern Mopars and swapped classics alike as they fit all the modern Hemis ('03 and up). They are the perfect pairing to long tube headers and are completely unique to DIYHEMI as they were designed in house.
Why our DIYHEMI O2 Extensions are better than the competition???
- Heavy Gauge Wire - Why? Newer O2 sensors (and vehicle electronics) are more sensitive to voltage drops than ever. Ours provides the lowest voltage drop in the market. You can feel the quality and heft in your hands.
- Universal Connectors - We designed these to fit pretty much all Gen 3 and 4 Hemis and possibly even more. No more grinding and snipping connectors. Compare the end connections to yours to see.
- Quality Loom - Our harness would not be complete without our signature quality soft braid loom. It helps protect against heat and abrasion while being extremely flexible.
- Upgraded Connector Locks - We've seen our competitors pieces fall apart. The red locking clip is the first to fail and could cause the extension to come loose. We re-worked these with the manufacturer to make sure it's not an issue.
Why OURS are the BEST!
Hey Guys! We know you've probably seen other O2 sensor extensions out there for Hemis but let us reassure you are getting the BEST ones here. We designed these in house from the universal connectors to the premium automotive grade (high temp rated) wiring.
