Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kit for Honda's K-series engines. Each kit includes Skunk2's high-quality dual valve springs and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm. Skunk2's industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2's already popular Pro Series Titanium Retainers, Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. Alpha Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures.

Cool Cuban Shirt
Size: Large, Color: Black Dark Gray
Looks nice and lightweight. I hand washed it and it turned out well. I used an iron to lightly press it. Overall the wrinkles were not bad. Would recommend

I just wish it wasn't vacuum packed.
Size: Large, Color: Black Light Brown
If the shirt wasn't vacuum packed to introduce bad creases/wrinkles, this would be a 5 star review. For the price, this is a nice and comfortable shirt. The thickness is really good for a polyester/spandex blend shirt; it's the right thickness for a summer shirt (because polyester doesn't breath at all). The rather small amount of spandex makes it just stretchy enough to give when moving. It wears a little like a fitted shirt, but it's not too tight at all for a bigger guys. It's not a loose fitting shirt, but it still feels like the correct size (my size was large). Note: This does have a bit of a V-Neck style, there's no button for the neck and the highest button is lower than most shirts. Unless you've a good iron with a steam feature, you're going to have a hard time safely getting rid of the wrinkles/creases from the vacuum packaging. This is a delicate fabric blend and high temperatures will permanently ruin it. I tried to quick wash and low temp dry in a machine with no results. Using a good iron on delicates/synthetics heat setting wasn't quite hot enough to undo the creases. Several steam blasts did wonders, but this was a time consuming process. You might get away using a drying machine at a higher heat for a short burst, but it's a risk. The stitching is good for the panels and arms. The different colors are different pieces of materials and not just dyes. The stitching at the bottom of the shirt, however, is jagged; not terrible, but it's a blemish.

Nice product but size is not as expected
Size: 3X-Large, Color: Green White
This shirt is really nice and really stands out only downside is the size isn't as expected. I usually wear a 2xl and decided to go with a 3xl and it was still a bit too fitted for me liking..Disappointed I couldnt use it
