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!

Won't open wide enough.
Size: Large, Color: 1-beige
The purse looks very good. However it only opens 4". It is very difficult to quickly find items when trying to make s purchase. Especially when there is a long line.

Bag is gorgeous! Rich shades of color!
Color: 1-shell Plus Brown, Color: 1-shell Plus Brown
I was expecting to return because of some of the feedback. Some said it is cheaply made, no lining, small, stiff. It is larger than I expected which is perfect for me and not that stiff, more sturdy and durable is what I call it. The shading on this one is like a mauve on the outside and towards the middle is brown and in the very middle, a dark olive green. The lining is really nice espresso brown with 2 smaller pockets, one large middle zipper and one zip pocket on rear wall. I haven't removed the plastic off the handles yet and off the hanging gold circle. Comes with the long strap for crossbody so exceeded every expectation for me. I feel that once it is filled and breaks in a little, it will look richer and richer. This was worth every penny for me and probably going to be my favorite every day bag!

super deal !!
Color: 1-colorful Blue
i got this purse on a special deal pricing for 19.99 & wow what a steal...........its a well made purse........vibrant color....its more a matte finish instead of shiny.........and if ur familiar with brahman this would be the small duxbury style...........im so glad it was the smaller one because the large duxbury is just awkwardly too big for petite gals like me lol.............very happy with my purchase & so glad i found this company............im an avid brahman fan as well & when i saw styles that brahman discontinued & now this company has them i was very happy :) these are excellent dupes but keep in mind they are dupes & price range is super so lining may be a bit thinner but not a deal breaker for me - lining was fine enough to hold up & instead of leather they use vegan leather - but dont be scared lol the vegan leather they use is very heavy duty & will hold up............im not a fan of vegan leather but i made an exception for this company............please keep making this style as well as the other styles u have - im a super fan !!! (ps- the small duxbury is still in use by brahman - its not discontinued - others styles on this companies websites are discontinued by brahman - so if u dont want to pay over 200.00 then this is an excellent option )

Well made, stylish handbag and a eye-catching color
Color: 1-bright Orange
I am very happy with the look and quality of this handbag; the fabric inside, and especially the deep, rich orange color I ordered - it does not appear to be available right now. I am glad to have chosen a solid color over some of the varied tones that appear harsh and cheap. I have not used the shoulder strap yet; the handles are comfortable to carry on the arm. I generally buy leather purses only so it is a pleasant surprise to be enjoying this vegan material, which looks more expensive than the price I paid.
