What made you choose this particular product?
Was looking for a good intake with some top end power. I've heard nothing but great things about these and now I know why.
Is this your first time buying from this brand? Did you consider other brands?
Yes. I considered trick flow but I honestly don't like the look of their intakes lol.
Was it easy to install? Any installation tips that will help others?
Fit like a glove. But my throttle cable bracket was too close, I ended up not even using my EGR delete plate and having to use an EGR spacer to clear the valve covers. It is VERY close to the hood. Keep that in mind. I planned on getting a bigger hood anyway.
Once you've had a chance to use the product, did it meet your expectations?
Far exceeded my expectations. The car feels like it can actually breathe now, and it breathes plenty on the top end.
Any additional comments?
Edelbrock parts are made in the USA. That's a big deal for me.
