The Wagner Tuning Side Mount Radiator for the BMW M3 and M4 (F80/F82/F83) is a high-efficiency cooling upgrade designed to support the demanding thermal requirements of the S55 engine.
Mounted in the factory side location, this uprated radiator significantly improves coolant stability during hard driving, reducing temperature spikes and helping maintain consistent engine performance.

Ideal for tuned, hybrid-turbo, track-driven or fast-road builds, the Wagner side radiator is a direct-fit upgrade that strengthens one of the S55’s most critical cooling pathways.


Key Features

  • High-efficiency aluminium cooling core

  • Increased thermal capacity compared with the OEM side radiator

  • CAD-optimised fin structure for improved heat dissipation

  • TIG-welded construction for durability under sustained load

  • Direct OEM-fit replacement

  • Helps stabilise coolant temperatures during spirited driving

  • Ideal for Stage 1, Stage 2 and hybrid-turbo S55 builds

  • Perfect addition to front radiator and charge-cooler upgrades


Compatibility

BMW M3 / M4 – S55 Engine

  • F80 M3

  • F82 M4

  • F83 M4 Convertible

(Not suitable for N55-powered M2 — use the dedicated F87 N55 cooling upgrades.)


Ideal For

  • Tuned and track-driven S55 setups

  • Drivers experiencing rising coolant temperatures under hard use

  • Cars running hybrid turbos, increased boost or high-power maps

  • M3/M4 owners wanting improved cooling system stability

  • Builds seeking additional thermal headroom alongside other cooling upgrades


Why Choose the Wagner Tuning Side Mount Radiator

The S55 engine generates substantial heat, and on many F80/F82/F83 cars the factory side radiator becomes a weak point under extended load. Wagner’s uprated side radiator offers a more efficient core with increased cooling capacity, allowing the engine to maintain safer temperatures during repeated acceleration, track sessions or high-ambient climates.

Benefits include:

  • Better coolant stability

  • Reduced temperature creep during hard driving

  • Improved reliability for tuned engines

  • Enhanced longevity of the overall cooling system

Wagner’s reputation for precision fitment and motorsport-grade cooling components makes this side radiator one of the most effective supporting upgrades for the S55 platform.


Installing / Notes

  • Direct bolt-on replacement

  • Works with OEM or upgraded front radiators and charge coolers

  • Professional installation recommended

  • Cooling system must be properly bled after installation

Love the new pillows! Even though there smaller than my last larger pillows. I would recommend these pillows if you do just want a smaller fluffy ones.

The king size pillows do not offer the same firmness and comfort as the standard size.
Color: White, Size: King (Pack of 2)
I buy a lot from from Amazon and this is my first negative review as this was one of my biggest disappointments. I have bought 7 sets of this Basic pillow in the Standard size over the past 4 years, for my home and my boyfriends, using them both to sleep on and for my pillow shams. I love these pillows and my guests do too, best sleep ever and I have tried a number of expensive pillows prior to this. So when I recently purchased my first king size bed, I bought two sets of the king size pillow of this same brand, and I hate them. They are not the same as the standard size as they are flat, and no matter how much I tried to fluff them up, they fall flat in filling and firmness. After a few restless nights using my new king size pillows, I used the standard pillows I purchased in the past and there is definitely a difference. I see where there are different reviews/opinions on this, but this has been my experience. I will be complaining to Amazon, though not sure there is anything they can do since I used them.

Ok, not as good as before, put in dryer to fluff!
Color: Grey, Size: Standard (Pack of 2)
I have ordered these a few times in the past and loved them. This time they came rolled up and vacuum sealed. Doing that made the pillows flat and feel worn out. I was going to return them, but read that putting them in the dryer on low heat for about 15 minutes helps fluff them. I did that and it definitely improved the pillows. I'll keep them, but they're def not as good as they were a few years ago.
