Improve transmission durability and cooling on track and road with do88’s upgraded transmission cooler – designed to handle the extra heat generated by tuned G8X models without compromising shift speed or gearbox life.

Overheating Risks in Tuned G8X Cars

The ZF 8HP automatic transmission fitted to the G87 M2, G80 M3, and G82 M4 is impressively capable – but like many OEM parts, its cooling system was not designed for extended track use or heavy tuning. With increased power and heat comes greater stress on the transmission cooler. Overheating can cause:

  • Slower, less consistent gear changes

  • Reduced transmission life

  • Limp mode or transmission fault warnings

Designed for Performance

  • +71% increased core volume vs. OEM

  • +50% increased cooling surface area

  • Dual-pass flow for longer fluid residence time

  • Upgraded harmonica-style tubes with internal channels for improved oil flow

  • Optimised design with no increase in oil pressure

  • 42% increase in oil volume (850ml vs 600ml OEM)

Motorsport-Ready Construction

  • Full aluminium construction for maximum strength and heat dissipation

  • TIG-welded end tanks for long-term reliability

  • OEM-style quick-connect fittings for hassle-free installation

  • Fits without any vehicle modifications

Fun Toy
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
My dog loves this toy. It has 2 squeaky & also has crinkly sound along with the slots for treats. However it is not very durable. The treat slots were pretty much destroyed with the first use. I'm still giving it a 4 star because it is so fun & entertaining for my GSD.

Kept puppy interested!... Till she chewed it apart in 5 minutes
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
I'll start off by saying this is a really unique toy. You really can hide treats in the pocket and the velcro is strong enough to roll it up that it won't come undone easily. The different textures and sounds interest my puppy! And she LOVES it! But it didn't last long with her. She LOVES rope toys and ripping them apart and eating it. I literally had just given it to her and not even a minute later (not joking), she had torn off a row of the rope-like part. 5 minutes later, the tail is already in shambles lol So long story short, great and interesting toy to keep the doggy from being bored. Maybe not so great for aggressive chewers/rippers in the long term. More than likely will be torn to shreds by the end of the day.

Great quality, fun design.
Color: No Stuffing Blue Eel
Wonderfully durable.. We have a 3 y/o australian kelpey and a 2 y/o pitty.. both are incredibly playful and tear up toys like nobody's business. A lot of the time under a day.. We're on day three with this eel, they love it and its holding firm (no tears or missing pieces). Squeakers are their favorite and these ones are perfect ( prominent but not too loud)

Sturdy
Color: No Stuffing Blue Eel
It’s has held up pretty good for my aggressive chewer dog. She typically tore these types of toys apart immediately. One of the ears she pulled off right away but the toy itself has stayed intakes (so far). It keeps her occupied long enough and she drags it everywhere with her.

size is small
Color: No Stuffing Blue Eel
Smaller than I anticipated but my dog enjoys it. After 3 days it is already getting ripped a little bit where the treats get hidden so not sure how long it will last. My dog is about 40 lbs.
