I've seen several threads re: bad gas mileage...
I think I'm gonna replace my two near the engine.

Questions are:

1) Is it a good idea to get factory (don't want to get stuck with any "old" ones in their inventory that has problems) and how much are they?

2) Aftermarket? I'm looking for direct swap (no splicing). I heard Bosch ones are good and fairly cheap... any experiences/comments?

TIA

 

Are you getting check engine codes? If not yu might be wasting your money. Try the basics if you are getting bad mileage. Plugs and airfilter is a good start.

 

Yeah change your Fuel Filter if you havn't done that yet..

no Codes.. no need to change.. but since you asked..
