Hey I thought I would just let everyone on here know I found really good prices on the NTK 02 sensors. As some of you know, these are the sensors that come in the Mopar box when you buy them at the dealership parts counter. Previously I had been buying them at www.sparkplugs.com. The 4-wire versions were about $48 through them.
I just bought a bunch of parts from Rock Auto, including some various 02 sensors. Check out these prices:
1 wire NTK O2 sensor #23004 (1985 Shelby Charger): $12.58
3 wire NTK O2 sensor #23005 (1987 Dodge Shadow): $25.99
4 wire NTK O2 sensor #23023 (1991 Dodge Spirit R/T): $28.89
I don't mean to sound like an advertisement for Rock Auto, but holy cow I guess I know where I'm buying O2 sensors now. These aren't even "wholesaler closeout" prices. Hope this helps some people out there save money.
