Vance & HinesO2 Sensor Port Plug Kit - 18mm x 1.5 16925

Add anti-sieze to threads before installation and torque to specs

Good fit & does what's it's suppose to & NO leaks!

First of all, Vance & Hines makes great looking and quality pipes, but at a price. I just don't know why these things are so expensive, but as a Harley owner I've become accustomed of spending a lot for accessories for my bikes.The pipes came with 18mm o2 Sensor Ports, however my 2003 Deuce does not have the o2 sensors, so I needed the O2 Sensor Plug Kit required for 1986-2006 models. This was not mentioned on the Amazon listing, so I did not order them when I ordered the pipes. Now I am waiting a week for the plugs so I can drive my bike. It is mentioned on the Vance & Hines site, but I thought that I needed the kit if I had o2 sensors, not the other way around. My mistake I guess, but if it had been clearly stated on the Amazon listing, I would not have made this mistake.Having said that, my other problem with the o2 sensor plugs is that they are $20 for two plugs. After paying almost $700 for the pipes, now I have to shell out another $20 for the plugs. These plugs are worth a dollar each at the most, and I think Vance & Hines should include them wit the purchase of the pipes.I probably should have gone to the local hardware store first to see if they had any 18mm screws.

If you got a sportster that doesn't have O2 sensors these plugs are required. Very durable and great quality, works as it should. You'll need the 18mm if youre planning on getting the Vance & Hines Short Shots.

Purchased with V&H Dresser Dual Headers for a 2004 Electraglide Classic (no O2 Sensor) exhaust upgrade. Super easy to install.

Ordered pipes and didn't realize I needed these plugs so I ordered them late and they came in early and fit perfectly

Fit good

Seems to work without any leaks so far.
