K-Tuned’s new velocity coupler is made from reinforced 4-ply silicone. This unique part completely removes the step commonly found at the throttle body opening, which straightens and accelerates the intake airflow and in turn helps the engine breathe easier. Intake system design and overall airflow into an engine can be critical to making maximum power. The coupler has been engineered to improve an engines volumetric efficiency similar to the way a velocity stack works. Other examples of improving airflow include port matching and tapering throttle bodies. When using a regular silicone intake coupler it always leaves a step at the throttle body opening, which slows airflow and causes turbulence. By installing the K-Tuned coupler, air turbulence is eliminated and the taper will help to increase the intake air velocity.

This will fit the most commonly used 3” intakes on the market. One end is custom fitted to the OEM 62.5mm K-series throttle body (cable versions) and the other end matches up to a 3” diameter intake pipe.

Great value, great quality.
Color: Black/Black/ Black Digital
My husband bought this watch for work. He can’t have his phone on him at work so this watch has been very useful for him. He sweats a lot and works in a warehouse. He has a nicer “church” watch I bought him as a wedding gift and he actually has started to prefer this one. There are only two little annoyances (which might be able to be fixed) every hour the clock beeps and that the alarm goes off every morning including weekends. Those things might be features which some desire and some that even we are impressed by so 🤷🏻‍♀️ as I said, those minor issues might be fixed if we look into them but my husband doesn’t find them as bothersome as I do and he’s the one who wears it.

Would definitely recommend this watch.
Color: Black/Black/ Wjite Digital
Nice manly watch. Many Timex watches are too small. I love the size of this one and yet it's still lightweight. The face of the watch is neatly organized and very clear to read. Indiglo light works well at night. Only thing I see missing from this watch is a countdown timer. It has a stopwatch.
