Turbochargers operate at high temperatures. The Cool Down Timer is designed to keep the engine running when the ignition is turned off to prevent turbocharger bearing failure that could occur when the engine is shut down, stopping the cool lubricating oil flowing to the turbocharger while it is still hot. If the oil flow is shut off too early, the remaining oil in the bearing housing will overheat causing coking of the bearings which causes both premature bearing wear and reduced oiling of the bearings. Allowing the engine to idle to a minimum operating speed gives the turbocharger time to cool down. The CDT is adjustable for up to 5 minutes of idle time, or optionally works with any K-Type EGT probe for temperature-based shutdown. Installation Instructions Installation Instructions

Great Service very knowledgeable staff, my ram is running perfect

This company lies to you. Ordered a 02 sensor from APPD for my C7 Vette. Paid the highest possible courier service for the fastest possible shipping from Newcastle to France. I needed the part urgently. Ordered at the weekend and called them Monday to confirm all was in hand and explained the part was required urgently. Response from APPD yes we've recieved the order and will ship as soon as its been processed. Called every day for the next 7 days to be told yes its been shipped and this is the shipping number. Turned out it took them till Friday ..5 days later to post it and then the package lay at the courier another week or so. APPD lied to me throughout this whole transaction. The package cleared customs in 2 days and should have been with me in just over week and not over 4 weeks. APPD offereed the postage refunded after I had to start a PAYPAL dispute.. This should have been a straight forward simple part delivery.When it goes wrong you shouldn't lie to your customer. A serious compay would refund the customer not try to fuzz the truth and blame everyone else. I refused the postage delivery refund so you can buy some honesty pills and discuss with your team how to avoid more negative service feedback. If your thinking of ordering parts from APPD scroll on and find another supplier. You dont need or want the hassle of dealing with these people.

Over a month waiting on parts and all I get is it will scan soon week after week. Reordered from US so I could finish build and same parts arrived in one week. Waiting to see if they will refund??
Gareth weare
placed an order for parts 13th of feb, all listed in stock, got shipping update for label created on the 16th of feb. I have still not received what I ordered and paid for, no updates. I have been getting the same generic answer "order will be fulfilled today" for nearly 2 months now when trying to enquire. Quite disappointing as I have been unable to finish off my car due to waiting on the final fuel system parts for over 2 months now.
PHILIP HYDE
I initially ordered the wrong part but managed to change the order before it was sent out. Lovely product Really well made.
Chris Impey
Made my first purchase with these guys, very helpful and quick replies to my questions.
Delivery was very quick, will be using again
