I bought this as my car is just past 100,000 miles and has no evidence of a sensor change... This part comes with the correct plug so electrical connection is a piece of cake... More difficult is the removal of the old sensor, heat shield and air-con piping all get in the way. You will need a 22mm spanner/split socket (it would be helpful for mx5parts to list this on the website), as I didn't have the correct size :)
I have not noticed any change in engine operation, which is probably a good thing as the old sensor didn't cause any ECU fault codes... I hope to see some fuel economy, as I have noticed the idle, zero crossing at a slightly higher frequency, so it definitely has a faster response than the old one.
