Why a Summer Tune-Up Matters: Ignition Coils, Misfires, and Money Back

A summer tune-up is not about a calendar, it is about catching the small problems that quietly cost you power, fuel, and reliability before a long hot drive. One of the most common culprits is a worn set of ignition coils, and from July 1 through August 31, NAPA AutoCare Centers across New Mexico are pairing that fix with a prepaid card rebate on a full coil set.

• A rough idle, hesitation, or check engine light often points to worn ignition coils
• Failing coils waste fuel and can damage the catalytic converter if ignored
• A full ignition coil set earns a prepaid card of up to $25 through August 31

What Ignition Coils Do, and How They Fail

Ignition coils deliver the high-voltage spark that fires each cylinder. They work thousands of times a minute, and over years of heat cycles they weaken. When a coil starts to fail, the spark gets inconsistent, the cylinder misfires, and you feel it as a rough idle, hesitation on acceleration, or a loss of power. Often the only obvious sign is a check engine light, which is easy to put off until something worse happens.

Because coils tend to wear at a similar rate, replacing the full set at once restores smooth, even performance and prevents the next one from failing a month later. It also protects the catalytic converter, an expensive part that unburned fuel from a misfire can quietly destroy.

The Rest of a Real Tune-Up

A proper summer tune-up looks beyond the coils. It is the right time to check spark plugs, filters, and the rest of the ignition and fuel system, so the engine runs clean and efficient through the hottest, hardest-driving stretch of the year. Better combustion means better fuel economy, which matters most when the air conditioning is running and the trips are long.

Claim Up to $25 Back This Summer

Through August 31, a full set of premium ignition coils (minimum four) earns a $25 prepaid card, and an economy set earns $10 back, on purchases made between July 1 and August 31. If your engine has felt less than sharp, this is the season to fix it and get money back.

Ask your local NAPA AutoCare Center of New Mexico about a summer tune-up and the ignition coil rebate before August 31.
