Volvo S80 2.4T Denso Injector Service

Decided to clean and service the stock Denso injectors. Rubber rings get hard and brittle over time and tend to leak. Also the filter baskets might be contaminated over time, especially if the fuel filter is not part of your regular service intervals (which mine S80 lacked…).

I bought this kit of Aliexpress and the quality looks very nice. It contains all the items needed, including a special tool for removing/mounting the filter baskets.

The pictures will speak for themselves (it was needed!).

Volvo S80 2.4T Changing Spark Plugs (NGK K20TT 4604)

Fitted some fresh new plugs and decided to try NGK copper plug instead of Volvo OEM Iridium plugs. They work great and cost next to nothing. Decided to try NGK K20TT 4606. Double checked the gap to be sure, they are correctly preset for the Volvo S80 2.4 / 2.5T.

Still have to get used to swapping out 5 spark plugs instead of the “usual” 4.

Volvo S80 2.4T Do88.se Blue Silicone Intercooler Hoses

Replaced some old deteriorated intercooler hoses with new fresh Do88.se blue silicone hoses, which do not collapse anymore. I solved a hiccup when flooring the car from low rpm (due to sturdiness of the new hoses).
