Skunk2 Ultra Series Stage1 Camshafts for Toyota Supra MK5/BMW B58 significantly increases engine efficiency and power output by utilizing advanced lobe profile designs that retain full Valvetronic and Double VANOS functionality, which ensures the widest possible powerband with smooth drivability and idle. For the ultimate in precision and strength/rigidity† Skunk2 Ultra camshafts are machined from forged solid 8660 alloy steel blanks that are then rifle drilled, induction hardened, and CNC precision ground.
Expect gains of 6% to 10% from 3,500rpm to redline with approximate gains of 100hp and 100lb-ft at 40psi boost pressure. Though Ultra Stage1 cams are compatible with stock OEM valve springs, we recommend the use of Skunk2 upgraded High Lift Valve Springs along with Titanium Retainers (PN: 313-14-1000) for the B58 as long term durability using stock valve springs is unknown.

When pushing performance, all OEM B58 camshafts are prone to bend due to the thin cam barrels designed to save weight and cost. Skunk2 Ultra Camshafts are made from high strength alloy steel and feature a thick-wall barrel design to better resist camshaft flex.

*Note: Actual results will vary based on engine condition, other parts selection, and tuning abilities.

Features:

  • Billet 8660 Alloy Steel Camshafts
  • Retains Double VANOS + Valvetronic fuctionality
  • Improved Efficiency / Power
  • Widest Possible Power Band
  • Smooth Driveability & Idle

Excellent quality and value
This is my 4th Maelreg 1/4 zip shirt. I've lost a lot of weight and looking for clothing that fits well and doesn't feel like a shirt from China. I found that the quality and fit are excellent. The fabric is soft, well made and slightly heavier than other 1/4 zips I've purchased on Amazon. The weight of fabric gives a quality feel. The styles of Maelreg pullovers are great. I get a lot of compliments on these shirts.

MAELREG Clothing Looks Great!
Love this quarter zip. MAELREG makes some comfortable, sharp looking clothing. Their golf apparel is fantastic. The value is worth it. Their shirts are true to size. I am 6', 215lbs and wear an XL, which fits nicely.

Great for Tall Guys
I got this for my husband, he has a pullover that he has worn for years and it needed replacing. Finding one like this that was lightweight and loose fit was a big challenge. He loves the quality and fabric and its not hot but still helps when their is a breeze or chill. I liked that the color and pattern are versatile for all seasons. He is 6'5 and it actually fits his torso! Just get it!

It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
