Dinan Semi-Open Intake - BMW / F-Series / B46 / B48Looking for more sound than what can be attained from the standard Dinan closed box intake for F2x F3x B46 B48 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. Beyond the additional sound
Looking for more sound than what can be attained from the standard Dinan closed box intake for F2x/F3x B46/B48 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.
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 a major factor 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 which robs the factory system of potential power. These two 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 B46/B48 engine to elicit gains of 6 HP and 6 TRQ at 5000 RPM on a completely stock vehicle.
Not to be outdone by the performance side of the equation, the B46/B48 intake also is completely made up of carbon fiber unlike 4-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 B46/B48 carbon fiber intake is a modification that is a must for any enthusiast that places sound atop their requirements list.
Features:
- More Power: + 6 HP @ 5000 RPM & + 6 lb-ft @ 5000 RPM (+ 5 WHP & + 5 WTQ) without additional modifications
- A pronounced sporty sound courtesy of a semi-open design
- Improved throttle response
- Larger volume air box (30% larger than stock) for increased breathability
- 34% increase in filter area (stock: 76.3in², Dinan: 102.1in²) for optimum flow
- Optimized carbon fiber intake tube
- Free flowing injection molded Air Mass Meter housing (ove 20% larger then stock)
- Quick and easy installation
- 50 State Emissions Legal (partial application list): CARB EO D-176-56 (2019-21 F2x/F3x 230i/330i/430i Only)

This mat works so well for my kitty!
Color: Gray, Size: 18"x24"
This pet bed is such a smart find! Someone had the smart idea to make a bed that stays cool in the Summer and warm in the Winter! The material on the Winter side is soft, snuggly plush with a foil layer to hold in the heat. Flip the mat over and it’s the perfect cooling mat for Summer, with a cooling ice silk fabric to keep cool. The mat is the perfect size for a small dog or a cat. Spot cleaning is recommended as the preferred way to clean but the listing says that it can be washed using the gentle cycle. It needs to be air dried however. My cat wasn’t impressed to begin with, but once she got a little playtime with her favorite toy and some catnip, she settled right in. This is a good mat to fit right into her crate for traveling.

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.
