BMW Radiators for BMW 3 Series E46 (1999-2005)

Ditch your failure-prone plastic end tanks and increase cooling capacity by 25%—all without modifying your core support or accompanying shrouds. This Performance Triple-Pass Radiator is the ULTIMATE cooling system upgrade for your S54-equipped BMW!

The E46 M3 is a masterclass in German engineering. Harboring six independent throttle bodies, infinitely variable dual-VANOS, and an 8,000 RPM redline, the S54 is practically a racing engine for the road. Unfortunately, the engine's motorsport pedigree didn't quite make it to the cooling system. The OEM radiator, while superior to its non-M counterpart, struggles to keep coolant temperature in check under sustained high-RPM conditions. Heat soak, elevated operating temperatures, and component fatigue are all too familiar to M3 owners who track their S54 regularly.

To solve this problem, we teamed up with CSF Race, a global leader in high-performance cooling solutions with over five decades of industry experience. Together, we developed the CSFxTurner Triple-Pass Radiator: a high-performance, no-compromise solution built to meet the cooling demands of track-day warriors.

Part Design:

CSF-Exclusive "B-Tube" Technology Unlike conventional "O-tube" designs, CSF’s patented B-tube structure increases wall strength while creating a more efficient flow path. This alone accounts for a 15% increase in cooling capacity over an OE "o-tube" radiator! Triple-Pass Core Design As the name suggests, this unique structure forces coolant through the core three times before exit, resulting in a substantial temperature delta across the radiator core. Two-Row Compact Structure This radiator was designed with precise fitment in mind. While total tube count and size are increased, the overall radiator dimensions stay the same as OE, ensuring a drop-in fit with zero modifications required. 25% Increase in Cooling Capacity All of the above design features translate to a massive 25% cooling increase over the stock radiator! Features & Performance Benefits:

Direct-fit upgrade—no modifications required! Accepts all OEM attachments via CNC-machined "Quick-Connect" hose ends and accessory mounting provisions TIG-welded aluminum construction provides increased durability An all-aluminum drain plug replaces the weak OE plastic unit, ensuring seamless functionality for the life of the radiator Increased cooling efficiency for high-performance and racing use Designed and tested by Turner Motorsport in collaboration with CSF Race

CSF is one of the premier cooling product specialists available on the market thanks to designs such as their High Performance Aluminum Radiators. Using a single pass designed core, this radiator gives you all the cooling you could ever need. Paired with these radiators are CNC machined brackets and corrosion resistant hardware that allow final installation to have a same as stock fitment! This enables you to have much higher cooling without having to cut away any metal or delete any important components just for the sake of lower coolant temperatures. 

Features:

• Two-row, triple-pass design radiator core
• CNC machined mounting brackets
• All needed hardware included
• Hand polished aluminum with a mirror-like finish
• Stock fitment prevents modification to engine bay

Fits the following BMWs:
1998-2006 E46 BMW All Submodels
2002-2008 E85/86 BMW M Coupe & M Roadster

The BMW E30 / E36 / E46 Offset Lower Radiator Mounts are designed to provide enhanced support and positioning for the radiator in BMW models, specifically the E30, E36, and E46. These mounts are a practical upgrade for vehicles that require extra clearance, especially when using aftermarket or larger radiators in performance builds.

Key Features:

1. Offset Design for Increased Clearance:

   • The offset configuration of these mounts offers additional room, making them ideal for accommodating larger radiators or custom cooling setups. This ensures proper fitment, especially in high-performance or modified vehicles.

2. Stable and Secure Mounting:

   • These mounts provide firm support to keep the radiator securely in place, preventing unwanted movement or vibration, which is crucial for maintaining the cooling system’s efficiency during intense driving conditions.

3. Durability and Heat Resistance:

   • Built from high-quality, heat-resistant materials, these mounts are designed to withstand the rigors of both daily driving and track use. They ensure long-lasting performance even under high temperatures and stress.

4. Optimized Cooling Performance:

   • By ensuring the radiator is properly aligned and secured, these mounts help maximize the cooling system's performance. Proper positioning allows for efficient airflow through the radiator, which is vital for preventing overheating during demanding driving situations.

5. Easy Installation:

   • These offset radiator mounts are designed as a direct-fit replacement, making installation simple and straightforward. They are compatible with the BMW E30, E36, and E46, allowing for an easy upgrade to support larger or performance-focused radiators.

6. Perfect for Modified and Performance Builds:

   • Whether you're upgrading to a high-capacity radiator or modifying your vehicle for improved performance, these mounts offer the extra flexibility and stability needed for customized setups.

Benefits of Upgrading or Replacing:

• Extra Clearance for Larger Radiators: The offset design allows for better fitment, especially when upgrading to a larger or aftermarket radiator.
• Prevents Vibration and Damage: These mounts reduce the risk of damage caused by vibration or radiator movement, ensuring longer-lasting performance.
• Enhanced Cooling Efficiency: Properly securing the radiator ensures that it can work at peak efficiency, leading to better cooling performance during high-demand driving.

In summary, the BMW E30 / E36 / E46 Offset Lower Radiator Mounts are an excellent choice for enthusiasts looking to upgrade their cooling system or accommodate a larger radiator. Their durable construction, ease of installation, and offset design make them a valuable addition for performance builds or maintaining cooling system reliability in modified BMWs.

BMW E46 AAF Aluminum Radiator Mounting Kit provides a robust solution for mounting an aluminum radiator into the BMW E46 chassis without relying on the stock plastic mounts. Developed by Advanced Auto Fabrication, a company renowned for their expertise in producing high-performance race car components, this kit reflects their extensive knowledge and dedication to BMW race car design.

The mounting kit is designed to replace the stock mounting system and is compatible with lightweight aftermarket fans, as the stock electric fan cannot be used. Please note that this kit does not fit M3 models.

• Durable Construction: Made from high-quality aluminum for strength and longevity.
• Enhanced Cooling Efficiency: Allows for the use of aftermarket fans for improved cooling performance.
• Race-Ready Design: Reflects Advanced Auto Fabrication's expertise in BMW race car components.
• No Stock Plastic Mounts: Provides a more reliable and robust mounting solution than the factory system.

Mishimoto E46 Aluminum Radiator features -

• All aluminum construction
• More durable and longer lasting than plastic components
• 20% more capacity in the same space
• Excellent fit and finish
• Unbeatable lifetime warranty and accident-forgiveness

Mishimoto radiators address all of the defects of the stock E46 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto radiator is an all aluminum design that replaces the factory plastic and aluminum stock radiator. The stock plastic end tanks are notorious for cracking and leaks whereas the Mishimoto has aluminum end tanks that will never fail. Mishimoto can also build 30% more coolant capacity into the a radiator that fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less super heated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat!

Mishimoto was established in 2003 as a supplier of cooling components for drift and rally cars. Their radiators and intercoolers soon found a strong following in the hyper competitive drift scene where high horsepower and prolonged high revs dictate the need for durable and robust cooling solutions. The catchy Mishimoto name is a combination of the name of the founder's family pet - Mishi - and "moto". All products are designed and tested in the USA using state-of-the-art CAD tools and prototyping and with continuous evolution of product design. Mishimoto is so dedicated to quality that they offer a limited lifetime warranty and accident forgiveness.
