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.

Good protection for your tablet.
Color: Navy+Black
Nice case although not as adjustable as my previous one it wears well and protects my iPad well. Its look does not detract from the tablet.

Comes apart easily.
Color: Black+Red
Bought my toddler an iPad for Christmas. Great feel, good quality but pops front pops off very easily when he drops it. I wish it would stay on a little better so I will be looking for a new one.

This iPad case is amazing! It fits perfectly, feels very durable, and gives great protection against drops and scratches. The design is super cute and the buttons and ports are easy to access. I also love how lightweight it is while still feeling sturdy. Definitely a great purchase and worth the price!

Cute and sturdy IPad cover.
Color: Purple Rose, Size: Case for iPad 9th/8th/7th Generation
Perfect cover for an iPad. I bought it for my 4 year old granddaughter’s iPad and she has dropped her iPad so many times and it stayed protected. The colors are cute girly colors. I love this cover. The handle turns all the way around and stands the iPad vertically and horizontally as well. Would definitely buy again.
