I just ordered new plugs and wires from RockAuto Auto Parts. I wanted to stay with ACDelco, so I called the local shops and ACDelco themselves. The plugs are the iridium plugs, item 41101. There were two options for the wire set, 746BB and 9746BB. When I called ACDelco, they said that the 9746BB meant they were the generics that would fit more vehicles or something; therefore, the 746BBs are the OEM replacement. The guy also told me that RockAuto was an authorized dealer and that the manufacturer warranty was supported by RockAuto and ACDelco. Sounds like a good deal to me!!

Has anyone else done business with RockAuto? Any hints for success and faster replacement on these bad boys?

Thanks!

 

I haven't purchased from Rock Auto but have heard good things about them from others.

Front plugs are no problem. I've found the back plugs easier to access if I first loosen the front engine mount dog bones. Allows the engine to shift giving a little more room back there.

 

I like to use ZSpot from NAIOA.com for my OEM parts. Usually using RockAuto as a basis for prices and part numbers.

Also Amazon.com surprisingly has good prices on ACDelco parts. I got my front o2 sensor from them for 1/2 the cost of RockAuto and ZSpot

But RockAuto seems like a reliable company to me also if you go with them.

 

When I was having a brief problem with O2 sensors (very brief), RockAuto was great. My stock O2 was dead, I got a Denso from Rock (reading on other forums it's the way to go), in a week the code prompting my original replacement of the O2 popped again. I saw on one forum a post of Denso having an issue like this and Delphi/AC Delco the way to go. Rock made an EASY exchange to a Delphi (per my request).

Despite their ease of pre-paid shipping to exchange, I wish I woulda taken Chibi's route to the AC Delco. OH WELL....

Ordered from Rock a bunch, 90% of the time, best price (good if you're not in a rush).

 

Ya, the prices were better than the local stores (because of their markup). And the guy that I talked to from ACDelco told me that they backed the manufacturer warranty from RockAuto, but would likely not back from other online sources...so I thought/think it will be a safe bet.

However Chibi, I am highly considering that same O2 sensor from amazon that you bought.

 

I bought the majority of my Delco parts from Rockauto when I tuned up my Monte last year. I actually bought the plugs on ebay cheaper. I bought Delphi plug wires instead of Delco because I've had bad problems with replacement Delco wires arcing on other vehicles I own so I skipped them on this car. My factory delco wires said Delphi on them anyway so I figured it was fine.

I like Rockauto and have not had any problems with them and I've bought parts from them on other occasions.
