MVS member Auburn T5 goes bananas on fixing up a 1998 Volvo S70 T5. Stage 0, new transmission, new struts, shocks and springs, you name it. Documented with photos too. Did a lot of stage zero work – inspected vacuum lines, changed oil filter, fuel filter, top motor mount, k&N panel filter, timing belt, water […]
Spark Plugs 1 – The turbo line that goes front to back will need to be removed. What I did was just remove the clamp ring towards the front of the line (because it is easiest to get to), but there is also one at the back. If you can do what I did, loosen the front clamp and pull the plastic hose out of the rubber.
To date no MAF sensors that were sent in failed due to the filter oil. In one of their tests they submerse a MAF in K&N filter oil and then take it out and and test it. Results were the same as a new clean one.
K&N does not filter as fine as your stock filter but the combustion environment is a messy one and the burt fuel supplies particles larger than the ones K&N lets pass through.
