do88 Radiator for BMW M2/M3/M4 (G8X)

Enhance the performance of your 2021+ BMW G8X M2, M3, or M4 with the do88 Radiator. This aftermarket radiator is expertly designed to improve charge air cooling when driving under demanding conditions.

Background

The S58 engine features a water-to-air charge cooler that works with a heat exchanger (water radiator) located at the front of the vehicle. This radiator cools the water circulating through the charge air cooler, effectively dissipating heat before it reaches the engine.

Challenges with the S58 Charge Air Cooling System

Tuned S58 engines may experience rapid heat-soak in the charge air cooling system, particularly during track use. High intake temperatures risk causing the ECU to reduce power output or result in limp mode. The do88 Radiator helps mitigate these issues by maintaining lower temperatures, thereby boosting both reliability and performance.

Our Solution

The do88 radiator has received a comprehensive redesign prioritising both durability and performance. Key features include:

  • Durable Construction: Plastic components have been replaced with sturdy aluminium for the end tanks, core, and CNC-machined ports. All joints are TIG-welded for enhanced durability.
  • Quad Pass Design: This innovative design allows coolant to pass through the radiator core four times, maximising heat dissipation.
  • Increased Core Volume: The core volume is enlarged by 39%, along with a 9% increase in the external tube area, which works together to improve cooling capacity.
  • Fluid Capacity: An increase of 1.4 litres in fluid capacity enhances heat dissipation.

Installation

The do88 Radiator is designed for easy fitment using your BMW’s factory components. It includes custom rock guards for protection against debris, making it suitable for G8X M2/M3/M4 models with either automatic or manual transmissions.

Key Features:

  • 39% larger core compared to the original.
  • 2-row core that is 48mm thick for an increased active cooling area.
  • Quadruple-pass flow design for maximum coolant efficiency.
  • Higher cooling fins for improved airflow.
  • Full aluminium construction with TIG-welded end tanks.

Vehicle Fitment

This radiator fits the following models:

  • BMW M2 (G87) – Engine: S58 (Model years: 2023 – 202X)
  • BMW M3 / M3 Competition / M3 CS (G80) – Engine: S58 (Model years: 2020 – 202X)
  • BMW M4 / M4 Competition / M4 CSL (G82) – Engine: S58 (Model years: 2020 – 202X)

Upgrade your BMW G8X M2, M3, or M4 with the do88 Radiator and experience improved cooling efficiency and performance on demanding drives.

Great despite mild defect!!!
Size: Large, Color: Octopus - Multi Color
this is a great toy for my pup! I love goDog toys because they last a long time for my destructive Aussie. This is my dog's favorite toy right now. He brings it to me constantly for a nice game of tug-o-war. It did rip within a month but the rips are staying intact thanks to the method goDog uses to put these toys together. I would not drop the rating for this, but I will admit the bottom cloth used to sew all the legs in tears easily. It is doing well after I sewed reinforcement into them but it would be nice if GoDog found a way to reinforce that piece to improve the toy.

Emotional support
Size: Large, Color: Octopus - Multi Color
Greatest toy ever! My dog is in love! This is like her emotional support toy. She sleeps with it and chews on it throughout the day. The only issue is the seams break open and the stuffing pops out after awhile. I just grab needle and thread and sew it back closed. Washes well too.

It lasted over a week- amazing for the fogzilla!
Size: Large, Color: Monkey - Green
There is no dog toy that can survive big puppies with strong jaws and sharp teeth, but the squeaker lasted a week and the arms/ legs are still intact. She's still playing with it, so I'm impressed.
