MSD Ready-to-Run Ford Distributors are the perfect upgrade for the bulky DuraSpark systems or ancient breaker point models. These distributors come complete and ready-to-run. All you need to do is drop it in the engine, connect three wires and fire the engine. Each distributor features an ignition module that produces a powerful inductive spark to improve combustion of the fuel mixture resulting in quick starts, smooth idle and increased performance. The billet aluminium housings of these distributors are 5/8" smaller in diameter to accommodate induction setups and tight engine compartments. A maintenance free magnetic pick-up is responsible for triggering the high voltage sparks while a sealed ball bearing guides an oversized shaft. Beneath the bolt down cap and MSD Race rotor you'll find MSD's accurate mechanical advance assembly. Different advance springs and stop bushings are supplied so you can easily tune a curve to match your needs. Plus, there is a vacuum advance canister to increase economy on long drives.

Easy to use
Size: 36 pcs
Great quality. Worked great on first try. Pulled out a sheet metal screw from my work van tire, reamed it out with the tool, inserted the plug and pulled it out first try. Tire is holding air perfectly. I would definitely recommend this kit for anyone whondoesnt mind plugging a hole in their own tire.

Good, but far from pro grade
Size: 36 pcs
It’s a good to carry on the back of your rig product, but one can tell it’s a made in china quality deal and would not hold up to full time working duty. For the price it’s a ok deal

Quick and easy solution tire kit
Size: 36 pcs
This tire repair kit has been great to keep in my EV9, Model 3, Model Y, and Lexus RX for emergencies. The tools feel strong and durable, and it gives me peace of mind during road trips and daily driving. I’m very thankful I had this kit because you will never know something or someone may puncture a hole in your tire! Especially living in California! Saves time and money on specially if you’re out far from home and no time to wait for a tow truck.
