Looking for more sound than what can be attained from the standard Dinan closed box intake for F2x/F3x B58 powered vehicles and don't want to sacrifice all the performance gains or the beautifully crafted carbon fiber design in the process? This semi-open variant of the same intake meets those demands using a revised lid with an additional auditory port so those intoxicating turbo noises can be more easily heard. When paired with the optional turbo inlet the full intake tract to the turbo is effectively replaced for further audio enhancement. Beyond the additional sound opening the semi-open intake takes the same path to success as its closed box counterpart. Improve upon the factory design by increasing flow via a larger airbox and filter element thereby improving throttle response and lessening the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign are major factors in ultimately producing a more potent intake, they are not the only variables in creating a more efficient design either. The devil is in the details which is where Dinan thrives. Dinan engineers focused their attention on the intake pipe itself where numerous improvements could be made. In factory configuration, the intake tube comes complete with baffling and a small Helmholtz chamber to reduce unwanted sound. As a byproduct, these features also cause a more turbulent airflow path that robs the factory system of potential power. These 2 specific details are diametrically opposed to our intended market's desires so the removal of these features was paramount. Through numerous iterations, a carbon fiber intake tube was developed that eliminated flow disruptions and allowed the natural sound of an unimpeded intake tract to sing. All told this thorough methodology of design allows the Dinan carbon fiber intake for the B58 engine to elicit gains of 15 HP and 13 TRQ 6000 RPM on a completely stock vehicle. An impressive feat on today's turbocharged engines. Not to be outdone by the performance side of the equation, the B58 intake also is completely made up of carbon fiber unlike 6-cylinder intakes of previous generations where a mix of materials were used. Not only is the intake completely carbon construction but the quality of the material has been improved as well. While looks are surely important, and this piece has that department covered in spades, the improved construction and coating also guarantees that the appearance of the engine bay with the Dinan intake will not be marred over time. Built to elicit a more pronounced sound, imbue the engine bay with some carbon class, perform, and last the duration-- the Dinan semi-open B58 carbon fiber intake is a modification that is a must for any enthusiast that places sound atop their requirements list.

Features:

  • More Power: + 15 HP @ 6000 RPM & + 13 lb-ft @ 6000 RPM (+ 13 WHP & + 11 WTQ) without additional modifications

  • Free flowing injection molded Air Mass Meter housing (8% larger then stock)
  • Quick and easy installation
  • 50 State Emissions Legal (partial application list): CARB EO D-176-56 (2019-21 F2x/F3x M240i/340i/440i Only)

My dog loves it
My Aussie loves it and he is a tough chewer as well, so it goes great with his hyper reactive personality. Durability could have been a little better, sometimes I have to take it apart and make sure it’s still in a good position because my dog will pick it up and drop it. With no cushion it did start malfunctioning at about 2 weeks. However, it does still work fine and he loves it even without the movement. Note if you put it in a sock to protect it, my dog goes dangerous and held the sock and created a slingshot lol.

My Rottweiler loves it!
My Rottie plays with this for hours at a time! He loves it! It fun to watch too! The plastic is high quality and has lasted for 2 weeks, so far. That pretty good for a Rottie toy! He loves the lights, vibration, and the fact that it rolls away. So fun!

Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.
