Bewährte Ermüdungstests: Die „Severe Duty“-Ventile wurden strengen Ermüdungstests unterzogen. Im Normalbetrieb werden Ventile einer Belastung von 20.000 bis 25.000 Pfund ausgesetzt. Wenn Ventile auf dem Ventilsitz aufprallen, steigt diese Belastung auf 40.000 bis 60.000 Pfund. Manley-Auslassventile, die bei 40.000 psi und 1400 °F getestet wurden, haben eindrucksvoll bis zu 100.000.000 (einhundert Millionen) Zyklen überstanden. Im Gegensatz dazu versagten die Angebote der Konkurrenz bereits nach 100.000 Zyklen und wiesen eine erstaunliche 1000-mal bessere Lebensdauer auf.Entwickelt für Benzinmotoren mit hohen Temperaturen: Entwickelt für überlegene Leistung in Benzinmotoren mit hohen Temperaturen.Chromschäfte und harte Spitzen: Einbeziehung von Chromschäften und harten Spitzen für verbesserte Haltbarkeit und Langlebigkeit.Optimierte Verbrennung: Wirbelpolierte Bereiche unter dem Kopf und vollständig bearbeitete Verbrennungsflächen für verbesserte Luftströmung und Verbrennungseffizienz.XH-428 für Auspuff: Kein Konkurrent weltweit bietet das außergewöhnliche XH-428 als Auslassventilmaterial an. Es weist bei 1500 °F im Vergleich zum EV-8 der Konkurrenz eine fast doppelt so hohe Zugfestigkeit auf.NK-844 für Einlass: Unser Einlassventilmaterial NK-844 ist ebenso unübertroffen und weist bei 1000 °F eine über viermal so hohe Zugfestigkeit auf wie das beste Einlassventilmaterial der Konkurrenz.

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??

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.
