Not all camshafts are created equal. You need to be very careful when choosing a new camshaft for your car, as choosing the wrong one can significantly drop your engine’s power.

Upgrading a camshaft is a very technical and complicated subject. Here are a few different factors of a car’s performance that a Kelford Cams camshaft can improve and deliver:
• Increased engine torque
• Improved RPM performance
• Enhanced horsepower
• Better engine idle smoothness
• Higher engine speed performance
• Superior fuel efficiency

Again, it’s not as simple as drop in a camshaft & you go faster. Several factors change depending on your car and what you require. Results will vary based on a number of options. For better understanding please watch video and/or review questions and answers below.
