I replaced my OE knock sensors with some cheap Ebay ones that were $10 for the pair. Those lasted 2 days. I bought these Hex knock sensors for my 03 Lexus RX300 and I've had them installed for 3+ months so far with no problems out of them. I had been dealing with faulty knock sensors for almost a year and I'm glad I replaced them, the power is a night and day difference!
