K&N Engineering is a manufacturer of cold air intake systems, air filters, oil filters and other aftermarket performance parts. They manufacture over 6000 parts for various cars, SUVs, trucks, motorcycles and more. Founded in 1964 by Ken Johnson and Norm McDonald, hence the name of the company K&N. The duo first sold motorcycles and motorcycle parts and also supported K&N factory race team. Not long after, they saw a need for air filters that can perform under extremely dusty and dirty conditions which prompted them to move into air filters, and that quickly became their primary focus. They have maintained an active involvement in racing over the course of their history. Including the King of the West 410 Sprint Car series and NASCAR series East and West. This on its own shows pedigree, and the quality of products being churned out from their factory.

Solid Basic Dress Shirt With a Slightly Small Fit
Color: Grey, Size: XX-Large
This shirt is pretty decent overall for the price. The material is on the thinner side, but thankfully it doesn’t have that overly shiny look that a lot of cheaper dress shirts tend to have. It still looks fairly clean and presentable, and it works well for business casual wear or occasions where you just need a simple button-down that looks put together. Fit-wise, I’d say it runs slightly small. It’s not dramatically off, but if you’re between sizes or prefer a little extra room, sizing up might be a good idea. Other than that, it’s a solid basic shirt that gets the job done without looking cheap.

Order a size up
Color: Black, Size: X-Large
Whatever their size chart says order a size up and it will fit perfect. The size chat suggests a large for me. I read some reviews and ordered extra large and it fits perfect.

Great for a growing kid
Size: Large, Color: Sky Blue, Size: Large, Color: Sky Blue
Good quality for a good price. My teen is outgrowing his medium clothes and into larges so it fit slightly big which I expected but that just means he should be able to wear it to his fall dance as well. Nice material, not see through at all even after dancing all night and sweating. Exact color blue as pictured. Very happy over all.
