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.

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

Stylish and inexpensive
Color: Grey
Great watch. Came in quickly from seller. Got it sized at a local shop. It’s a pretty stylish watch for the price point. I don’t have big wrists but I still think the face could be a little bigger. But it’s pretty sleek and I’m happy

Swiss Quality from a good brand
Color: Grey
This is my 4th Tissot watch. I only have a few quibbles. The band adjusts by removing wide or narrow pieces, not by adjusting with pins with a range of holes. I prefer that way to adjust a metal band. The color blue of the dial is darker in real life than the picture. I also wish the day indicator was a little larger (or my eyes were younger).

A LOT of watch for the money

I purchased this piece with low expectations but was pleasantly surprised by the quality and overall esthetics. If you are a young man looking for your first watch that doesn’t break the bank, this is the one.
