Thanks for the how-to. Sounds like the driver side is going to suck

I also replaced the Duralast coolant temp sensor that I installed a year ago that I think was bad from the start. I'm done with all Duralast parts at this point.

As for replacement, follow what 92 SVX said. Remove the alternator and you'll have access from the front side. I was able to get the driver's side sensor by doing that, which is farther back and harder to get to, but I have small, skinny hands so I tend to have less issues reaching things in tight spaces than most people.

I try to keep the times when I use off the shelf brands to a minimum and like most its about $$. OEM is just crazy expensive for knock sensors but the lifetime warrenty for most of these aftermarket ones make it a little more reassuring if need be. I actually had replaced two Bosch knocks on my Legacy that never seemed to work well with an Advance brand (forgot) which has kept the CEL out for sometime now.
