Review on Spectra Premium C 511 Coil Plug by Aaron Harwood

When I tried this automotive product I was amazed at the instant improvement in my car's performance. The Spectra Premium C 511 Coil Plug added better acceleration, smoother idling, and a noticeable increase in horsepower.It was an easy installation and fit perfectly into my vehicle. The only downside is that it's slightly more expensive than other coil plugs on the market, but the improvement in performance is worth the extra cost. Overall, i highly recommend this product to any car enthusiast looking to upgrade their ignition system..
