SPA Performance has developed a must have for 911 Turbo (997.1) builders.

The stock manifolds are made out of plastic, which may work well for the stock engine, but when it comes to getting more out of this engine, this may be a limiting factor.

With that in mind, SPA Performance has developed manifolds 100% made of cast aluminum, with 5mm wall thickness, which will allow builders to work further on this engine, with no worries regarding the intake manifolds’ integrity.

SPA Performance has also developed a 100% cast aluminum plenum, aiming for higher flow values and ready for higher boost levels.

Comparing to the stock, SPA Performance’s plenum has a higher internal volume and it is made out of aluminum, which is much stronger than the stock one, made of plastic.

The manifolds are available in two options: 1 injector per cylinder (6 injectors) - bolt-on option, compatible with stock fuel system – and 2 injectors per cylinder (12 injectors) – for higher performance builds. For the 12-injector option, it features a pair of billet aluminum fuel rails, with -10AN inlet and outlet. The fuel rails are nickel plated for corrosion resistance and received a black electrostatic paint for a great surface finish. Both manifolds are offered with a high durability black wrinkle paint.

The plenum was designed to work with an 82mm throttle body (not included in the product), standard on the Porsche 911 997 GT3, which ensures greater flow for the set.

Stock hoses and clamps (not included) must be used to fix the manifolds and plenum.

  •  Application: Porsche 911 Generation 997.1 Turbo and GT2 (3.8)
  • Material: cast aluminum (manifolds and plenum) / cast aluminum (fuel rail).
  • Number of injectors: 12
  • Contents: 2 intake manifolds (right side and left side), 1 plenum and in the case of intake manifold for 12 injectors 2 fuel rails (right side and left side).
  • Plenum ports: 1/8" NPT.

Comfort Meets Performance — Nike Men’s Journey Run Road Running Shoes
Size: 10.5, Color: Black/Summit White/Anthracite/Cyber
I picked up the Nike Men’s Journey Run Road Running Shoes on a whim, and they turned out to be a great surprise. From the first wear, they felt comfortable and lightweight, with cushioning that makes walking and running on pavement much easier on the feet. They don’t feel overly stiff or bulky, which I appreciate for everyday use. What I like most is how versatile they are. I’ve worn them for short runs, gym workouts, and even casual outings, and they’ve held up well in all situations. The fit is true to size, and the upper feels breathable enough to stay comfortable throughout the day. They also have a clean, simple look that pairs well with both athletic and casual clothes. Traction has been solid on roads and sidewalks, and I haven’t noticed any slipping, even on slightly wet surfaces. While they may not be designed for competitive racing, they’re perfect for daily training, walking, or anyone looking for a reliable, comfortable running shoe. Overall, the Nike Journey Run shoes offer good comfort, dependable performance, and everyday style. A solid choice if you want a no-nonsense running shoe that you can wear beyond just your workouts.

Versatile sneakers. The upper makes the difference.
Size: 11, Color: Black/Smoke Grey/Medium Ash
Very good quality shoes for this price. My impressions: 1. The Flyknit upper feels very soft and comfortable. I don't get the rough, scratchy feel of some lower-quality options. It also disperses heat very well. 2. The midsole is firm, but not overly hard. I find it well-balanced, as it has good shock absorption while still being soft enough to cushion the soles of my feet. 3. They're versatile. For me, especially the black ones with the dark gray sole, they work for casual wear, going to the gym, walking, and short, light runs. 4. I consider them very decent shoes for walking and short runs under 5k.

Offer lots of support and traction- perfect gym shoes
So comfortable- they offer a lot of support and I can tell they will last for a long time (and I’m hard on my gym shoes!). I’m actually a female but I sized down and they fit perfectly. I found them on sale and definitely recommend them as they are well worth the price.
