Replaced the air filter and the turbo intake pipe.
The intake pipe was upgraded to a blue Do88.se / Do88 silicone intake pipe, which is a fair bit larger, but also deletes some bottlenecks from the original part (like the narrowing bend on the bottom and the “harmonica”).
Gives a little bit more power from the butt dyno and noticed more intake growl (which is a good thing) 🙂
My original gearbox mount was shot and I decided to replace the mount with a brand new reinforced polyurethane mount, which tightens up the shifting and allows for less engine movement, which is better for the exhaust.
One disadvantage, the cabin has added drone due to extra vibration. But the advantages outweigh the one disadvantage, so for me it’s a keeper!

Old vs New. The mount should not be able to move like that 🙂
And this is how it looks under the engine. Easy job, 2x 14mm & 2x 18mm nuts.
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).
I wanted to try an open filter, to hear the induction sound and the blowoff sound. I went with a big velocity stack type filter. Although it sounded nice, I already reverted it and went back to the original airbox.
And it looks like this again
A highly recommended repair / modification for all older Volvo owners. Replacing the old rubber vacuum lines with strong durable silicone hoses. I bought 3 color hoses (red / black/ blue) as the original hoses also have color stamps on them. Old rubber hoses deteriorate from heat and moisture and will fail over time. Replacing them with silicone hoses ensures a proper running car!
