Q1: What is a Knock Sensor?
A1: A knock sensor is an automotive component that detects sudden, sharp vibrations from an engine, caused by a phenomenon known as engine knock or detonation of fuel-air mixture. The sensor then sends a signal to the engine control unit (ECU) to adjust the ignition timing to prevent engine damage.
Q2: Why is a Knock Sensor important?
A2: A knock sensor is very important in maintaining optimal engine performance and protecting the engine from damage. By detecting and responding to the onset of engine knock, the ECU can adjust the ignition timing to prevent engine damage.
Q3: How often should I replace a Knock Sensor?
A3: Generally, a Knock Sensor should be replaced every 75,000 miles or so, depending on the driving conditions and environmental factors. In some cases, it can be replaced as quickly as 25,000 miles. It is important to follow your vehicle manufacturer's recommended maintenance schedule for best performance.

Ring RTC Tyre inflator
Bought the tyre inflator because of the unreliable service station tyre inflators.
The buying process online through APD was straightforward. Ordered the tyre inflator late afternoon and received it 2 days later via the Royal mail.
I have a car, campervan and motorbike. I like the wind in cable feature keeps everything neat and tidy. The inflator is easy to use on all three vehicles. Appreciated the chocolate.
Very quick despatch and delivery time
Good updates. Items exactly as described. All fitted and car back on the road.
Personally I found them to be very...
helpful response to emails relating to my purchase was within the hour and they offered the best price on the parts I needed had to wait a couple of days longer than usual due to the parts that I needed was out of stock (but I was made aware of this before ordering) would happily use them again.
Very helpful company.
I ordered a cabin filter on their website which was out of stock. They contacted me by email & offered a replacement which wasn't really what I wanted so they immediately sent a refund. I found another that was suitable, they happily ordered it for me and called me when it arrived in my local store to collect.
Helpful people giving great service
The Wiper blades I ordered were competitively priced and promptly delivered. Unfortunately there was an issue with the fitment and this is where APD showed their commitment to great customer service. They were most helpful in resolving the problem to my complete satisfaction.
