Product Details

The Wiseco K666M855AP is a high-performance piston kit engineered for maximum durability and power output. This complete piston set features Wiseco's renowned forged aluminum construction, designed to withstand extreme cylinder pressures and temperatures in demanding performance applications.

Key Features:

  • 85.5mm bore diameter for precision fitment
  • ArmorPlated (AP) skirt coating reduces friction and wear
  • Forged aluminum construction for superior strength-to-weight ratio
  • Complete kit includes pistons, rings, wrist pins, and circlips
  • Precision-machined ring grooves for optimal seal and oil control
  • Dome or dish design optimized for compression ratio
  • Made in the USA with Wiseco's aerospace-grade materials

Wiseco pistons are manufactured to exacting tolerances and undergo rigorous quality control testing. The ArmorPlated skirt coating provides enhanced scuff resistance and allows tighter piston-to-wall clearances for reduced noise and blow-by. Ideal for street performance, racing, and engine rebuild applications where reliability and performance are critical.

So I left a review already about autoplicity and it was before I even checked when it was going to be delivered. I was happy to see it was already shipped but even more excited and pleased to see that it was only going to take two days to get here! Scheduled for delivery tomorrow! Could not be any happier with this company!

Great service! Will be doing more business in the future.

Easy to shop. However, I couldn't tell how long it is going to take for me to receive my merchandise. I'll know for sure how satisfied when my product arrives.

Smooth

Very easy to use. Like the association with amazon.

thanks

Excellent payment options and no hassle.

Great price! Super easy and I love that you give the ability to pay through Amazon.com! I feel very comfortable and safe using Amazon.

Where others couldn't deliver Autoplicity could. I went through two other supplier who kept changing the ship date. Autoplicity had it in stock and shipped the next day.

Received the order in 3 business day. Price was the best. Tried the VIAIR 400p that I order and found it to me my expetations.

Easy to order!

Quick and easy. Best price.

slight hiccup with payment, but paypal triumphed over Amazon!
