Hawk 1.6L 16 Valve Re-Grind Replacement Cams
We have carrier many cams in the past and have settled on one brand for its high quality and performance gains. The Hawk cams cannot be beat. Other cams we have seen are low quality and use old technology. Not the case with these cams. For the 16 Valve we have the Touquer 260 cam that will give great low end power and torque and is great for those looking to crawl those hills and rocks. Power band will be in the 1000-4000 RPM range. Requires modified intake rockers that are included in the kit.

Regrinding a cam seems kinda questionable...
How does it work do you like it.
Does it help millage sense it gives you power in the range that you use, or hurt it for that reason.
Does it add much power in that range for crawling and starts.
and anything else you know about the product how is hawk as a company.
