Frequently asked questions

The AD Auto Parts ignition coils and OEM SP541A double platinum spark plugs are designed for compatibility with the Ford Escape, Focus, Transit Connect, Mazda Tribute, and Mercury Mariner. It's essential to verify the specific year and engine type of your vehicle to ensure proper fitment.

Spark plugs typically should be replaced every 30,000 to 90,000 miles, depending on your vehicle's specifications and the type of spark plug. Ignition coils, on the other hand, can often last the life of a vehicle, but it's common to replace them after around 100,000 miles or if you notice issues like misfires, reduced fuel economy, or difficulty starting your engine.

Many car enthusiasts with moderate mechanical skills can replace ignition coils and spark plugs on their own, as it is a relatively straightforward process. However, you'll need the appropriate tools and to follow a proper guide or manual specific to your vehicle model. If you're not confident in your ability to carry out the task, it's recommended to seek professional assistance.

OEM SP541A spark plugs typically come pre-gapped to meet the specifications required for the intended vehicles. However, it's always a good practice to check the gap before installation as it can sometimes be altered during shipping or handling. The installation process does not involve gapping the ignition coils.

I purchased a Set of 4 ignition coils and 4 OEM SP541A Double Platinum Spark Plugs, neither of which work in my 2020 Ford Transit Connect. The offer must include the models and years of vehicles that the products are designed to fix. Now I have to pay the return.
