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 Alarm Siren Module fix

As a lot of older Volvo’s, my S80 showed the cumbersome “Alarmservice needed” message. I decided to search for a fix instead of buying a new one, which costs about €280 – €300, which is a lot of money.

The process is very simple, slicing open the siren, disconnecting the battery pack and plugging in the new battery pack. The hard part is to remove the security bolt, I used a angle grinder and then tapping it out. I used a normal bolt when I mounted the siren again.

I bought it here: https://www.ebay.com/itm/152151139597

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).
