Do those things really work check it out at www.spiralmax.com or maybe u already know about them please let me know if they really work and how much horsepower increase u get out of it i have a 98 Civic DX coupe

Thanks

Typical range of improvement over baseline is:
0 to 35 increase in horsepower,

0 to 31.85% increase in fuel economy.

HAHA. Notice the 0 part of the 0-35% increase in hp? Well, you may gain 35% on a 1 or 2 hp engine. but 0% sounds more like the actually outcome.

Basically this thing spins the incoming air to help it enter the cylinder at a faster rate then it would normally. Now, if you had a sperate spinner for each intake runner (or real velocity stackc) this would work. but since you install it before the manifold all of the spiraling effect goes away before the air even gets to the cylinder.

This question has been posted many times before and it seems many companies are trying to trick uninformed customers into buying this peice of overprieced metal. I would avoid this thing at asll costs.

i called them up yesterday and i asked them how much horsepower increase i would get and they told me it would be 15-18 for my car they said if u don't get that much horsepower u can return the product

im sorry but i highly doubt you're gonna get that much more HP out of your car with that.

Now what about nice air filters? Like K&N filters, do those give u more HP?

in theory a K&N can free up some power but it all depends on the way the car is setup initially. Most of the time you won't really see any noticeable increase by adding just a K&N. You will get a little more noise but not any noticeable power. Even so, I have bought one for each car I have ever owned.
