DO88 Performance Intercooler J-Pipe, Intercooler to Throttle Body

DO88 performance intercooler to throttle body J-pipe designed for an easy drop-in-fitment in your BMW M2 / M3 / M4 F8X

The S55 twin-turbo engine that powers the BMW M2C / M3 / M4 F8X is equipped with plastic intercooler pipes on both the hot and the cold side. These pipes are a weak link on any tuned car and in some cases even on a standard tune. The OE plastic pipes often crack / split leaving you with a boost leak.

With our performance intercooler J-pipe, we offer a solution for the reliability issue and of course at the same time minimise the restrictions in the standard pipe by improving the air flow!

To get an exact 3D-model of the available space to design our intercooler pipe, we carried out a detailed 3D-scan of our M3 Competition engine bay. With the help of this 3D-scan model we could design a new 3,5” (89mm) casting J-pipe with nice smooth routing. Most aftermarket J-pipes on the market are made of mandrel bent 3” pipes cut and welded in several pieces to achieve the J-shape. The OE J-pipe is 3,3” (85mm) so it is clear a 3” version is not ideal in terms of airflow, which we also have confirmed on our Superflow flow bench.

Our final design is a super durable 3,5” (89mm) casting J-pipe which improves the airflow. It has a free form shape with the same diameter all the way to the throttle body which is “impossible” to achieve with mandrel bent pipe. Our J-pipe has two methanol injection connection (1/8 -27 NPT) which is blanked off with plugs at delivery. A more durable silicone hose is also included together with matte black hose clamps for a clean stealthy look. A new C-clip is included to fasten the J-pipe to the throttle body instead of the flimsy OE plastic retaining clip.

Significant advantages with do88 performance intercooler J-pipe:

  • Improved reliability!
  • 6061 Aluminum instead of plastic
  • Stainless steel throttle body C-clip
  • Matt black silicone hose coupler included
  • Up to X% better air flow!
  • 2x 1/8-27 NPT connections that can be used for methanol/nitrous injection or as vacuum port fitting for pressure gauge. Blanking plugs are included!

A New Classic
Format: Kindle
I pre-ordered, so I was able to get the PDF and start reading early. Of all the books I own on the American Revolution, I think this one stands to become my "go to." It is encyclopedic in scope, but deftly avoids becoming a drudgery or a slog through a mire of textbook facts. Somehow, Eric has managed to include a great deal of detail without losing any of the drama. It’s the story that rises to the fore in a gripping tale that just happens to be true (and much more than that, is our heritage). All the trademark “Metaxas” hallmarks are here: judiciously placed humor and lightheartedness that never descends into silliness, seriousness that somehow never lacks in winsomeness, depth that never smothers. He manages to portray both the soberness that the subject deserves without losing the hopefulness that the story of the Revolution should inspire in us. And along the way, you’ll find yourself better understanding what “went down” and (just as importantly) what it means to you today. Excellent work. If you think another history book on the American Revolution cannot inspire you or keep your attention, this one is up to the challenge.

The History Teacher I Always Wished For
Format: Hardcover
With his trademark wit and his eye for those wonderfully absurd details that most historians tend to overlook, Metaxas drew me deeply into the story. I found myself laughing out loud one moment and profoundly moved the next. The tiny anecdotes and humorous asides were not distractions at all — they were precisely what made these towering figures suddenly feel human and unforgettable. Eric makes these historical figures flesh-and-blood again. He brings both heroes and villains vividly to life in a way that makes the drama of America’s birth feel immediate, thrilling, and deeply personal. In short, Eric Metaxas is the history teacher I always wished I had. At 600 pages, this book reads with the ease and momentum of a paperback novel, yet carries extraordinary depth and scholarship. In the end, I came away with a renewed love for American history and a deeper gratitude for the souls who made this great country possible.

A fun, inspiring, thought-provoking read.
Format: Kindle
A witty, learned page-turner, replete with wacky anecdotes but suffused by wisdom and patriotic love. Metaxas shows how the biblical view of the human person made America possible, and weaves throughout the story pieces of evidence that Providence actively aided the pious patriots against their cynical, post-Christian enemies in Britain. I devoured this book in 72 hours, and now I want to go back and read it again.
