Can I Use 2 Different Spark Plugs

Yes, you can use two different spark plugs in your vehicle, but it is always recommended to use the same spark plug type and brand for optimal performance. Using two different spark plugs can cause uneven engine operation and potentially decrease performance and fuel efficiency. It is best to consult with a mechanic or check your vehicle’s owner’s manual for the recommended spark plug type and ensure they are both properly gapped and installed correctly.
