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.

Great but slippery
Size: 3 Count
Always disliked how wash clothes are too gentle and soft. I don’t feel clean with them. This one however is very rough. Love it. I feel clean. I gave 4 stars b/c the cloth is very slippery. A bit hard to get a decent grip while using it. Literally slides right out of your hand.

Nice, but too small...
Size: 3 Count
...for dudes with bigger hands. The softer black side is very soft, but basically worthless if you're wanting to really scrub dead skin away. The white rougher side is really nice and after scrubbing with it, you really feel clean. You can really feel your pores come alive when you're rinsing the suds away. I've only used the rough side. Now the disappointing part is that the cloth is just too damn small. Men with larger hands will have a hard time keeping the cloth in your hand - it's not big enough to drape over your hand so it scrunches up quite a bit when you're really trying to get a good scrub with it. If they made these in a larger size I would easily give it a "5".

Perfect wash cloth, a soft side and an exfoliating side. Easy to clean I just throw it in with my towels.
