Clutch Masters and MC15017-BK

When upgrading your clutch, don't overlook upgrading your clutch master cylinder as well. Typically the OEM master cylinder will work just fine, but sometimes that master cylinder is getting old and tired and possibly might be leaking. Or maybe you want just a little bit more crisper pedal feel when operating your clutch. Upgrading to the Clutch Masters X Wilwood Clutch Master Cylinder will make sure your clutch hydraulic system is up to snuff and able to handle more aggressive driving. The other notable upgrade this kit will do for you is eliminate the clutch delay valve that is built into the factory master cylinder. The delay valve is a one way regulating valve that slows the fluid returning from the slave cylinder after you let off the clutch. This delay is especially noticeable in quick 1-2 gear shifts where you get back on the gas before the clutch is fully engaged. By getting rid of the delay valve, you are able to shift quickly and the clutch is immediately engaging.

This is a complete plug and play kit and includes everything you need to install this system. Will work with OEM slave cylinders.

What's Included:

  • Wilwood Master Cylinder
  • (.750" Bore) 3an stainless steel line
  • Fittings
  • Billet aluminum master cylinder adapter
  • Billet aluminum reservoir cap
  • Billet clevis
  • Hardware

Fitment:

  • Subaru WRX STI 2.5T 6-speed 2004-2014
  • Subaru WRX 2.0T 5-Speed 2002-2005
  • Subaru WRX 2.5T 6-Speed 2006-2014

MC15017-BK and Clutch Masters .75in Bore Master Cylinder Upgrade Kit - Black Subaru WRX | STI 2002-2021

Nothing like the original Eden, don’t buy the name
Team Name: Eden Cool+, Size: King, Color: Classic
I’ve had the original Coop Eden for 5+ years and it has been a great pillow, very comfortable, soft but supportive but when I purchased a new mattress I wanted to refresh my pillow and saw the Eden Cool+ and wanted to give it a try. I figured it could only be better than the original Eden…but it is not. While the outer cover is noticeably cooler to the touch, it is not soft like the Eden. Also, this cool material mostly gets negated if you use a pillow case anyway. The shaped fill material I would also say is “lumpier” for lack of a better word than the shredded material in the original. The combination of the harder, less supple outer casing and the lumpy material just aren’t a good combination. I will say it does sleep slightly cooler than the original Eden but not enough for the sacrifice in comfort. I would absolutely consider going back to the original Eden.

Unmatched Pillow with Unmatched Customer Service!!! 5 STAR ALL AROUND
Team Name: Eden Cool+, Size: King, Color: Classic
## A Dream Come True (and Customer Service to Match!) From the moment I first laid my head on the Coop Eden Cool+ pillow, I knew I'd found something special. It's truly a game-changer for hot sleepers like me. The "Cool+" technology isn't just a gimmick; it actually works to keep my head and neck comfortably cool throughout the night, leading to the most refreshing sleep I've had in years. The adjustable fill is brilliant, allowing me to customize the loft perfectly for my sleep style, which means no more waking up with neck pain. The support is fantastic – it cradles my head without feeling too firm, and it holds its shape beautifully. However, what truly elevates my experience to a full five stars, beyond the exceptional product itself, is the **dedicated and outstanding customer service**. I had a minor issue with my initial pillow (a rare manufacturing defect, which can happen with any product). I reached out to Coop Home Goods, and their response was nothing short of phenomenal. They were incredibly prompt, empathetic, and went above and beyond to resolve the issue swiftly and completely. They genuinely cared about my satisfaction and ensured I was left with a perfect product. It's rare to find a company that not only produces a superior product but also stands behind it with such integrity and genuine concern for their customers. The Coop Eden Cool+ pillow is an investment in your sleep, and knowing that you're backed by such an incredible customer service team makes it an even easier decision. Highly, highly recommend!

⭐️⭐️⭐️⭐️⭐️ Incredible Comfort – Like Sleeping in a Luxury Hotel Every Night!
I am beyond impressed with the DIORIS Pillows Queen Size Set of 2! From the moment I laid my head on them, I knew I had found my new favorite pillows. They strike the perfect balance between soft and supportive, making them ideal for back, stomach, and side sleepers like me and my partner. The fluffy down alternative fill feels just like the real thing—plush, breathable, and incredibly comfortable without triggering my allergies. These pillows don’t flatten out overnight either; they maintain their shape and bounce back beautifully each morning. What really stood out to me was the hotel-quality feel. The outer fabric is smooth, skin-friendly, and breathable, helping me stay cool and sweat-free throughout the night. I wake up feeling refreshed, well-rested, and with no neck pain—which is a huge win! If you're looking for affordable luxury, I highly recommend these DIORIS pillows. They’ve completely upgraded my sleep experience, and I’ll definitely be buying another set for the guest bedroom!

Helps you get a good night's rest
Color: Blue, Size: Queen Size Set of 2
These are my favorite pillows. I've had so much neck pain and headaches in the morning. This all stopped once I started using them. They hold up their shape and seem like they are good quality. My husband kept trying to steal my pillow, so I had to order him his own. You won't be disappointed in these pillows, and you'll get much better sleep.
