Default Knock Sensor for 2003 XJR

Hello,

I have recently purchased a 2003 XJR with a number of issues; the most pressing being needing a knock sensor. I have changed some over the years on my VDPs and I'm checking to see if the XJR sensor are the same? When looking online I have seen some that look quite a bit different. So the question is; are they the same sensors? I have attached pictures of the two I have seen...is it knock 1 or knock 2? Thanks a bunch!


Knock 2

Knock 1

Knock 2. The first photo. Do yourself a huge favor and change them both unless you enjoy pulling the supercharger off on a regular basis.

The bottom photo (knock 1) is for an earlier AJ26 engine.

Knock 1 is for AJ26 engines and Knock 2 for AJ27.

I have knock sensors for a '05 4.2 in mine, ...they've been in since '18 with no issues. You need to search around, because you can find deals usually, but you have to hunt. I found mine at NAPA for a ridiculous $67 ea.
