2005 Subaru WRX
I just received a quote from a local shop that I have come to trust and would really appreciate a little input from the guru's. I am starting to notice some (minor) hesitations on hard acceleration, which seems quite probable given the original spark plugs at 75k miles. I would normally consider giving this routine maint. a shot myself, but I no longer have an inside location to work on the car, or get it up off the ground enough to work on it. Due to Subaru dealerships changing hands in this area, I would prefer to take it to the local shop that I know.
Platinum Plug replacement = $170
Transmission fluid and filter change = $128
Front and rear differential fluid change = $122
Coolant change = $90
Terra-clean fuel system flush = $188
A few questions:
1) The local shop mentioned this car is a coil over system, no plug wires. Other shops that I called had no trouble quoting me cost on wires. Are there plug wires on this thing or not?
2) Some of the other shops that I received quotes from indicated that they would do the tranny fluid change, but not the filter. This particular local shop is doing both the fluid and the filter. Why would some shops charge nearly $100 just to cyphon out and replace fluid only?
3) I wasn't aware there was a front differential. Is this common for all cars that have front drive wheels? My knowledge of front wheel drive is very limited.
4) Has anyone had any experience with these fuel system flushes? It sounds as though they actually flush the intake, can this damage anything? I'm an old school guy, and never heard of this before, but the mechanics seem to REALLY encourage this as a very effective procedure at getting the car running as smooth as it did out of the factory.
The prices seem about right from what I can tell. Thanks in advance for any input or shared experiences.
