FULL-RACE 4 PORT MAC BOOST CONTROL SOLENOID

Our 4-port MAC boost control solenoid valve is designed to target a clearly defined boost curve and improve boost responses, and in some cases with a soft WG spring—quicker spool. The 4-port design works equally well in low boost and high boost applications. The 4 port MAC differs from a traditional 3 port MAC BCSV (boost control soleniod valve) because it precisely directs pressure to the open and close ports of your wastegate diaphragm. This allows for a much lower wastegate spring pressure for better low gear boost control and perfect high gear, high boost control. Low gear boost means more traction at launch and lower gears and higher boost at higher gears when traction is usally less of an issue. This is commonly refered to as "boost by gear"

  • MAC Part number – 46A-AA1-JDBA-1BA

FEATURES

  • Better spool-up time and mid-range power
  • Better duty cycle control to hit target boost and hold
  • The solenoid is normally closed so that on failure you will run off the waste-gate spring only – to prevent over-boosting.
  • 1/8th NPT fittings

COMPATIBILITY

  • Ideal for use in sealed Dual Port Internal WG applications, Internal or External
  • Hondata S300, K-Pro or Flashpro
  • Cobb Tuning AccessPort
  • All PWM modulated standalone and piggyback ECUs will support this 4 port BCSV!

Note: 4 Port MAC Boost Control Solenoid must be mounted upside down on B2 EFR frames. This allows the exhaust port to point towards the wastegate nipple. Use our mounting bracket. 

OPTIONAL UPGRADES

  • Full-Race Vacuum/Boost Block
  • BorgWarner EFR Wastegate Hose Kit
  • Fittings and Filter for 4 Port Boost Control Solenoid

Beautiful, and everything I want it except that the keyboard keys didn’t work😭
Color: Light Pink
I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.

Great quality case and keyboard
Color: Purple, Color: Purple
Super good quality case, I was actually surprised since it’s such a good price. It fit my 10.9 inch perfectly! Keyboard has magnetic attachment to the case which is super handy, and it connected with Bluetooth seamlessly. Keyboard isn’t silent, it’s on the louder side, but not too loud at all and it doesn’t bother me at all because I prefer clickier keyboards. Oh also something that’s really cool is that you can change the colors of the keyboard, love that!

Amazing!
Color: Midnight Green
The Hamile Keyboard Case for iPad (11th & 10th Generation) is a practical accessory for turning your iPad into a more laptop-like setup. Designed with a detachable wireless keyboard and protective case, it’s aimed at students, professionals, and anyone who types frequently on their tablet. One of its most appealing features is the 7-color backlit keyboard, which makes typing easier in low-light environments while also adding a customizable, stylish look. The backlighting can usually be adjusted in brightness and color, making it both functional and fun to use. The keys are generally responsive and comfortable enough for everyday typing tasks like emails, notes, and document work. The case itself provides decent protection for the iPad, helping guard against scratches and minor bumps. It also holds the tablet at a stable viewing angle, which is useful for video calls, studying, or streaming. The wireless connection is typically simple to set up via Bluetooth, and the keyboard can be detached when not needed.
