What warranty does Denso offer on their auto parts?

Denso Auto Parts offers a limited warranty on their products. The specific warranty coverage may vary depending on the type of auto part purchased. For Denso brand spark plugs, the warranty covers defects in materials and workmanship for up to 12 months or 12,000 miles, whichever occurs first. Denso starters and alternators come with a limited 12-month or 12,000-mile warranty as well. Additionally, Denso offers a 36-month or 36,000-mile limited warranty on their A/C compressors, fuel pumps, ignition coils, and oxygen sensors. This warranty ensures that the auto parts are free from defects in materials and workmanship during the specified coverage period. Warranty claims require proof of purchase, and Denso reserves the right to examine any part claimed to be defective before giving a replacement or refund.
