The Turbo L15B and K20C engines from Honda are high performance direct injection engines that have proven to make great power as well as deliver very good economy. The key to keeping your engine running efficiently is to ensure there is complete combustion (all air and fuel is ignited and burned in the combustion chamber). The best way to do this is to make sure your engine is fitted with a fresh clean set of NGK Iridium Laser Spark plugs. These spark plugs are the direct OEM replacement for the Honda part. (Honda rebrands these exact NGK plugs and sells them for more.)
As spark plugs age, get dirty and wear out the resistance through them increases making it harder for the ignition coil to create a spark that arks from the Spark Plugs electrode to the grounding strap. If the Spark Plug is not able to “spark” as described it causes a miss fire or what we refer to as “spark blowout”. 95% of the time this is simply caused by old spark plugs that need to be replaced. (Nothing like an easy cheap fix you can do yourself in the driveway!)
