Hey do you know if that one you posted will fit an '08 2.5?rear
remove sensor, install this part, then reinstall sensor.
just an example:
O2 Extender Oxygen Sensor Spacer HHO Test Pipe 1 | eBay
there are different lengths and even right angle versions if you need more clearance (will vary by year/model/heat shields...stuff). some folks use two of the shorter ones piggybacked together if one doesn't work.
friend of mine that owns a shop said he's been using the right angle versions as they don't make the sensor + extender so long that they run into things. but i haven't tried the right angle style yet.
it's so easy to do and works so often that i consider this the first step unless there's some compelling reason to work on something else.
well you should do a little research but all O2 sensors have the same thread pattern as spark plugs...been that way since like the 80's...probably 70's....so O2 sensor threads are rather standardized...that type of part fits like every subaru made for decades so i'm assuming yours too - but you should check, i haven't installed on on a vehicle as new as 2008 (but I'd bet a lot of money it's the same).Hey do you know if that one you posted will fit an '08 2.5?
Its not a VW, Audi, Porsche, BMW, Mercedes, Volvo, Caddillac or Saab. SoI have been reading over and over the threads on the p0420 code as it seems to keep popping up on my car. Here is my question could a leaking valve cover gasket cause enough of a vacume leak to cause this code?
