Price difference for Denso coils

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. The significant price difference of ignition coils for your RX350 between Amazon and AutoZone could be due to various factors, but it doesn't necessarily mean the Amazon coils are counterfeit. Amazon sometimes has lower prices due to third-party sellers, bulk purchases, or discounts. However, checking the seller's reputation and reviews is important to avoid counterfeit products. AutoZone tends to offer more reliable in-store warranty services, which might explain the higher price. If you're worried about authenticity, buying directly from a trusted retailer is always the safest route. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
