DIY: #Volvo T5 C30/S40/V50/C70 Spark Plug Replacement

Video tutorial on how to replace the spark plugs on a Volvo 2.5L straight 5 cylinder turbo’d engine. This car I am working with here is a 2007 Volvo C30 T5, but this same engine was also used on the S40, V50, and C70 Volvo models, as well as some Ford models. A similar procedure can most likely be used on other Volvo models too. Typically worn spark plugs can cause poor performance, poor fuel economy, delayed throttle response, poor idling, flat spots along the rpm range, misfire, and poor emissions. Bosch has provided me with the parts in order to do the replacement and produce the video for everyone.
