Set of 8 Round Ignition Coils D585 with Spark Plugs and 748UU 8mm Wires for Chevy and GMC Vehicles

Condition: Like New
Upgrade your Chevy or GMC engine with this premium set of eight D585 round ignition coils, iridium spark plugs, and thick 748UU 8mm wires for improved ignition, enhanced efficiency, and reliable performance.

This ignition coils bundle is engineered to bring new life to your vehicle’s performance. The set provides eight D585 round ignition coils, eight iridium spark plugs, and eight 748UU 8mm premium spark plug wires. Each component is specifically matched for optimal compatibility and synergy in your ignition system.

The D585 ignition coils stand out for their powerful energy output. Their construction uses tough materials to handle heat, vibration, and strain from long drives or tough roads. Powerful spark delivery means smoother starts, better combustion, and more power to your wheels. Drivers notice better fuel economy and reduced vehicle emissions with healthy ignition coils. Even in harsh environments, these coils are built to last and deliver consistent output.

Iridium spark plugs are an upgrade over basic copper plugs. Iridium is much harder and more resistant to erosion than traditional metals. Each iridium spark plug maintains a clean, efficient spark, so your engine starts quickly every time. The slim center electrode reduces electrical resistance and helps create a controlled, powerful burn inside each cylinder. This helps your engine idle smoother, start faster, and deliver steadier power throughout the rev range. With regular driving, these plugs last longer and need fewer replacements than standard plugs.

The included 748UU 8mm spark plug wires are designed for efficiency and durability. These wires transmit energy efficiently from coil to plug, making sure each spark is strong and consistent. The wires use thick insulation to block heat and interference, supporting a stable ignition signal. This reduces the risk of misfires and helps prevent unwanted radio or electronic interference. Each wire in the set fits snugly, helping keep the ignition components safe and secure even during vibration or rough terrain.

This ignition coils set is compatible with a variety of popular Chevrolet and GMC vehicles. Common fits include Silverado 1500, Silverado 2500, Silverado 3500, Tahoe, Suburban, Express, Sierra, Savana, and Yukon. Actual fitment can differ, so please check your model, year, and engine type first. You can also match OEM part numbers UF262, C1512, and 12622553. For more fitment details, visit GM engine resources on Wikipedia.

Installing this set can noticeably improve how your vehicle runs. Expect more responsive acceleration and smoother throttle control. Many drivers experience improved gas mileage and fewer emissions. Healthy ignition helps prevent engine knocking and reduces idling problems. A quality system like this makes a difference for anyone wanting consistent daily driving or better performance from their truck or SUV.

Drivers should replace worn ignition components early. Regular checks can prevent breakdowns, stalls, and engine warning lights. Fresh coils, wires, and plugs can extend engine lifespan. For more upgrades and parts, explore our automotive collection.

Ignition Coils Set: Frequently Asked Questions (FAQ)

• Question: How can I tell if these ignition coils fit my Chevrolet or GMC vehicle?
  Answer: This set of ignition coils covers many Chevrolet and GMC models, including Silverado, Tahoe, Sierra, and Yukon. First, check your owner’s manual for your model and engine type. Next, compare current coil part numbers (like UF262, C1512, or 12622553) to this set. It’s important to make sure they match to avoid compatibility issues. If you are not sure, you can use VIN lookup tools or ask a trusted mechanic for advice on proper fit.
• Question: Why should I upgrade to iridium spark plugs over standard copper plugs?
  Answer: Iridium spark plugs use a harder metal, which lasts much longer in hot engines. They provide a stable spark every time, so your car starts fast and runs smooth. Many iridium plugs require less voltage, making them suitable for modern and older engines alike. You’ll likely see better throttle response and improved fuel use. Over time, this switch means fewer replacements and better reliability, especially under harsh driving or frequent starts and stops.
• Question: Can I install this set myself, or is it better to use a mechanic?
  Answer: If you have some mechanical experience and follow steps from your service manual, you can replace these ignition components at home. Always disconnect the battery first for safety. Take care to install each part in the right order: start with the coils, then the wires, then the plugs. Use the proper torque so you don’t damage parts. If you have doubts, getting a professional’s help is wise. Bad installation can cause running issues, so always double-check your work.
• Question: What are some signs that my ignition coils, spark plugs, or wires need replacement?
  Answer: Look for engine misfires, rough idling, or delayed starts. Poor acceleration and lower fuel economy are common warning signs. You might see a check engine light related to the ignition system. Sometimes, cars may stall or have trouble passing an emissions test. These issues often point to old or worn coils, wires, or plugs needing replacement.

In summary, replacing your ignition coils, spark plugs, and wires can improve performance, boost efficiency, and extend vehicle life. Trusting quality parts makes every drive confident.
