Review on Genuine Honda 17670 SM4 A04 Fuel Filler by Jeremy Kakaruk

I love this gas cap, I had the engine light on the whole time because my Honda had a regular gas cap; my mechanic called me after the 4th or 5th time when I arrived thinking something was wrong; he advised me to buy a new gas cap, so i bought it first in the autozone, it didn't work, the check engine light came on; That's why I bought this gas cap and it's worth every penny; Since I bought it the check engine light hasn't come on and my gas mileage has gotten better because the vaporizer code doesn't come on every time I fill up with gas. AHA!
