Simple install-comes with instructions.  No tools required, installs in a few minutes.



A Technical Update:

The 2012-13 Sportster's , especially the 883, seem to do a bit better with the XIED's.




HD has changed the fuel maps due to emissions regulations. This has resulted in the 2012-13 Sportsters really liking the extra 2% fuel the XIED provides over the X14iED.

Not that any of the 2012-13 XL's will run bad with the X14's, they just respond better to the slightly richer XiED's.




2014-16/17 Model Update:

The FL-ViED-10 is the best product for all 2014-16 Twin Cam models.  

2014-17 Sportsters use the XL-ViED-14


They work inline with your existing H-D Bosch narrow band 02 sensors and Delphi ECM to richen the fuel mixtures, adding approximately 8% more fuel to the engine in closed loop mode.

There is an indirect richening of the open loop fuel mixtures through the learning mode, or adaptive fuel value action built into your ECM.  This ensures the richer 13.8-12.5:1 AFR's are ALSO adjusted in heavy/full throttle operation.


I installed Stage 1 slip-ons and air cleaner and then the XiED's. The low speed hesitation is gone and it is running 20-30 degrees cooler.  Talk about a simple install-best $99 I've spent on my 2011 Fatboy! -Roger


"409” ignition wires provide continuous heat protection up to 600-degrees Fahrenheit

Customer Reviews

Fantastic Review by John
2009 Street Bob. W/out a doubt, instant difference in temperature. Much cooler, even in stop and go. Slight increase in throttle response. You'd be a fool not to use these. I'm very impressed. (Posted on 9/8/2020)
Runs Cooler and More Responsive! Review by Mitch
Installed on my 2009 Super Glide Custom. The bike runs much cooler and the acceleration is much smoother. I lost the decel. pop that I was getting in 3rd gear. I have the Arlen Ness Big Sucker and the Vance & Hines Slip On's. The bikes exhaust even sounds better too.It took about 2 gas tanks for the computer to recognize the change. (Posted on 8/21/2020)
Just what I needed for my Road King Review by Mac
I have a 2007 Road King 96" with a K&N A/C kit, Screamin' Eagle 3.5" Street Cannon slip ons. I have a 1.75" louvered baffle in the left and 2" louvered baffle in the right. After reading a lot about this I was skeptical but I must say install was super easy. Bike runs 30Deg cooler. Throttle response is improved. Low end torque is strong and smooth. I can climb a hill in 6th gear. I can still make the bike pop on decel but I have to be trying to do it, won't happen otherwise. Be patient. I had no noticable change for about 300mi, but now it seems to have caught up. Love my bike even more now. (Posted on 6/26/2020)
Way cheaper than a tuner. Review by Clint
So I bought these for my 07 roadking and they were just the magical zing my bike needed. Bought the bike with aftermarket exhaust already installed but still have stock air filter. Once bike was at operating temperature it was almost to hot to ride, a common harley problem. When I installed these I also installed an Arlen Ness big sucker intake kit, between these two items my bike really came alive and doesn't run nearly as hot as before. Throttle response is crisp and smooth, no chugging at low speeds and can actually ride in 6th gear now without having to down shift all the time. After 200 miles so far my brand new plugs have a good tan and not snow white from running lean. Thank you for these, they really helped and changed my bike for the better, best of all they didn't cost me $800($400 for a tuner and $400 for dyno time to tune it). These fit the bill perfectly for an all stock bike. Super fast shipping to boot, what more could you ask for? (Posted on 1/22/2020)
XIED Review by Coconutnotwell
I put this on my 2008 96”road king all stock 5000k miles, I only rode for 8 miles and could feel the defense much better more response ,more fun to ride, thank you (Posted on 9/5/2019)
Cooler, smoother on lower octane Review by 08FLHTC
Very pleased with this upgrade! My 96ci Twin Cam is running cooler and I have switched to regular (87) octane without significant popping during deceleration. Little change in fuel economy and noticeably smoother running engine. If you have a 6 speed like me, increased responsiveness is really noticeable in sixth gear at lower RPM. What a simple improvement! (Posted on 7/24/2019)
No decel pop Review by Renzo
Have stage 1 on 07 nightster. Deceleration pop mostly gone. Acceleration has noticable improvement. Plug and play and saved me $300 over Fuel Pack. Highly recommend. (Posted on 7/22/2019)
Quick plug and play Review by BradX
Plugged directly in. Wires were short enough to hide excess. Only have 100 miles on them since I put them in. Almost no decel pop. (Posted on 5/7/2019)
XIEDs do what they’re supposed to do Review by Roy
The XIEDs were really easy to install and made a big difference to the way the bike runs. It’s noticeably cooler, smoother and the low speed surging is completely gone once the bike is warmed up. I wasn’t looking for a “race tune”, just something to make my bike run like it should’ve from the factory and the XIEDs do pretty much exactly that. (Posted on 4/15/2019)
