I have a 1998 Ford Escort SE 2.0l 4 Cylinder... E3 looks pretty sketchy and they sound cheap, so I don't want to buy those, but I definitely need new ones (150,000 miles and they PO did a crappy job taking care of the car)

Well...as far as power goes...they work...... More tests will have to be done on gas mileage but they do increase power at least on my Celica GT ...
