hi: I am planning to replace the spark plug for my car. I got the plugs directly from an online dealer (for cheaper obviously). my question is do I need to adjust the gap for this plug? It is denso iridium.
It would be a good idea to measure the gap before installing the plugs, the spec is 1 to 1.1 mm. I hope that you purchased the correct model iridium spark plugs; not all iridium plugs (even from Denso) are alike.
