Product Details

The Manley 613005C-1 is a high-performance single forged piston engineered for Mitsubishi 4G64 engines equipped with a 4G63 cylinder head. This Platinum Series piston features an 87mm bore diameter (+0.5mm oversize), 1.375-inch compression distance, and a dish-style crown design for optimal combustion chamber efficiency.

Key Features:

  • Forged from high-strength 2618 aluminum alloy for maximum durability and heat resistance
  • Precision-machined using Manley's unique "one fixturing" method ensuring perfect ring groove to skirt squareness
  • Cam and barrel skirt profiles provide substantial power while protecting cylinder walls
  • Contour forgings deliver optimal strength-to-weight balance without grain-interrupting internal milling
  • 22mm wrist pin with premium chrome moly construction included
  • Proprietary multi-step ring groove machining for superior ring seal and increased power output
  • Lightweight design balanced for long service life in demanding applications

This single piston is ideal for engine rebuilds, replacement, or custom engine builds. The dish design allows for tunable compression ratios depending on cylinder head specifications. Recommended piston clearance is 0.0035 inch measured 1.100 inches from the bottom of the oil ring land.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

very fast processing received product within a few days. fair prices. will do business with again.

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!
