PerTronix 91281 Ignitor II Adaptive Dwell Control for Ford 8 Cylinder

Works well,easy to install

Made a huge difference for my 65 mustang. Wish I would have done it sooner.

I'm not a gear head. Don't have a shop full of once-in-a-blue moon tools. I can change my plugs and fiddle with my carb- that's about it. But I have a 70' Ford F-100 with a 360 engine and I love my truck...way more than mechanical knowledge can express. Luckily, some awesome nerds got together some time ago and figured out a way to implement more modern firing and timing systems into the existing distributor.My experience with this product came as result of nearly having my ears blown off when my truck backfired. Everyone in the neighborhood ducked, getting up slowly to look around. I knew something was up before this happened. My truck had been having very rough acceleration. I thought/hoped it was my carb (cause I can mess with that). After some fiddling and the neighbors ducking a couple more times I finally found a mechanic who would answer my questions- turned out...duh, my points are off.Now I grew up with cars that were quiet and smooth and didn't have any of this points business. So naturally...I had no idea how to change them...or honestly how they worked. But I do know how to do math. My points were last set about a year and a half ago. It cost me about [...] bucks. I had seen the pertronix products in the LMC trucks catalogs. I figure if they improve my fuel economy/horsepower and give me smoother and more even acceleration response AND I can skip the trip to the mechanic every year then why not try them out. I also bought the flame thrower II (it's recommended). Total cost $[...].Install was really easy, although the instructions could have used some more diagrams and to have been a little more comprehensive/thorough. I guess they figure everyone who buys these products knows every inch of their truck...well not me and I wasted valuable minutes of my life pondering a few phrases. The only weird thing to watch in my particular install was that the starter wire goes on the left of the ignition coil now instead of the right. I already had premium bosch spark plugs...if you don't I highly recommend them. Also if you install this product you can play with your carb to make the mix a little leaner/thicker if you want. I would also adjust the idle while you're at it...my idle rpms jumped substantially from the added punch and precise timing.The end result has been fantastic. I feel like I have a brand new truck. It's so responsive through the whole rpm cycle. Reduced vibration. Improved fuel economy (very slight). But the performance is a huge improvement. I wish I had done this when I first bought my truck three years ago. Most people know some of the best money spent in improving a vehicle is done in the firing chain. This product is perfect example of that. It's given me the best driving experience my truck has likely offered in decades. Best of all my neighbors no longer cowar in fear when I drive by but instead wave and smile.

I replaced a Pertronix that I installed in my classic car 30 years ago with the Pertronixs II.Easy to install and works great. Installed in my 1968 Shelby GT 500 along with a 40,000 volt coil. Highly recommend.

I replaced the points ignition system on my 1971 Mustang with the Pertronix 91281 Ignitor II in April 2016. This ignitor works beautifully and the vehicle started and ran wonderfully. I decided to add the Flamethrower ignition coil a few months later and it started better than ever. Unfortunately, the car randomly wouldn't start one day in August 2017. I traced the problem to a dead Pertronix Ignitor. It just spontaneously died with no warning signs. After doing some research I found that the Ignitor II with adaptive dwell control has had more issues than the first generation Ignitor I. I overnighted a new Ignitor I from Amazon and installed it, and my Mustang is running beautifully. Thankfully Pertronix has a 30 month warranty on these units and I'll be pursuing that with them. I'll probably just keep the replacement as a backup in case my new one fails (it literally takes five to ten minutes to install, so even in a parking lot it'd be easy). If the first unit hadn't failed just after a year I'd easily give it five stars.

Getting no spark on my 71 f100 with pertronix system now have spark

Funcionó muy bien en mi ford F100 de 1962

This did not fit into my 65 Mustang 289 because there was an aftermarket distributor in my car when purchased. This will only work with Autolite distributors because the cam that lifts the points is larger in the original ford distributor. There is a plastic piece with the ignition kit that has to fit tight around the cam. Pertronix will tell you this.I gave this 5 stars because I bought the D130700 distributor that has this ignition in it and it works great. So with Amazon's great return policy, if you have an aftermarket distributor and this doesn't fit, you could get the whole distributor as an option.

Tossed it on my 360 in my f100. Works well, super easy to install. No more messing with points... Although that's part of the fun of old vehicles.

Lo recomiendo altamente, mucho mas precision y facíl de instalar

What a great product fitted into my distributor without any issues and runs better. Thankyou.

Funciona muy bien

Great alternative to old school technology. Easy to install with some patience.
