While I have the supercharger off I'm going to replace my knock sensors. For my 2000 XKR I found these products:

$23.83 Airtex 5S5619 Amazon
$28.99 Duralast SU7012 Autozone
$71.86 Standard Motor Products KS309 eBay
$105.70 Jaguar OEM LNE1692AA (it looks like they are made by DENSO) JaguarPartsCheap

Obviously the Aftermarket products are way more affordable but I'm worried it might be a major quality downgrade. Does anybody know about knock sensors?

 

cheap aftermarket works just fine, ive used them for many years, 0 failures.

 

Seaweed, be advised that SU7012 has a much longer cord than is needed for the XK8. Be sure to take the slack off with a tie up near the connection at the thermostat tower.

Thanks guys. Did both of you use the Duralast SU7012?

cjd777: How long have you been using them?

 

Seaweed, I used a couple on a friends car when he needed it right away and Autozone could have them that afternoon. So far no problem and it's been over 6 months.
We did both and I think it was really only one that had a ground issue after a thermostat leaking down the block but at the price, we just did both. The same one with a short lead was in the $70 range, go figure.
On another car having the same problem, cleaned the stud and bottom of the sensor, drove it a few days and it cleared, lucky.

I think some parts you can go with a cheaper brand. This part in question does not move, no moving parts, what really can go wrong?????

 

the only part on our jag, you should not do aftermarket is the alternator.

Its federal law, all aftermarket parts must meet or exceed oem quality.

Ive got $10 knock sensors in auctions new,

New Cheap Coils for under $40 bucks, all works great for many different cars, many different aftermarket parts
