2013 Cobra AMP Cell Pro Irons
Professional golfers hit the sweet spot on their irons with such regularity that when they’re deciding on a set, they’re more concerned with feel, workability and consistency than they are distance and forgiveness. For those golfers, Cobra has released its AMP Cell Pro forged irons, which don’t follow the current trend of making irons larger, hotter and more forgiving.
Instead, the AMP Cell Pros are actually smaller than their predecessor, Cobra’s S3 Pro forged irons. But for top ball strikers, the loss of size is worth what the irons deliver in abundance — a tremendously soft feel.
The S3 Pro forged irons were popular on Tour among Cobra Staff players for their clean lines and soft feel. The AMP Cell Pros have a similar shape, but shorter blade lengths — a change that allowed engineers to place more mass behind the sweet spot of the irons, which contributes to an even softer feel from the 1020 forged carbon steel heads.
“It’s inherent that the more mass you have behind the hitting area, the softer an iron will feel,” said Josh Breier, lead principal design engineer for Cobra-Puma Golf. “The added mass absorbs vibration.”
The AMP Cell Pro irons also have less offset, a thinner sole and more sole relief, as well as a different set makeup. Whereas the S3 Pro irons included cavity back long irons (2 through 6) and muscleback short irons (7 through PW), the AMP Cell Pro irons actually have three different types of irons in the set – dual cavity backs in the 2 through 6 iron, single cavity backs in the 7 and 8 irons and full musclebacks in the 9 iron, pitching wedge and gap wedge.
These three different types of irons allowed engineers to create a set with more “flow,” meaning the transition from long irons to mid irons to short irons is more gradual. The cavities of the irons gradually fade away as the set moves to the short irons, giving the AMP Cell Pro irons a more consistent feel throughout the set than the S3 Pro irons.

One of the tricks to adding weight behind the sweet spot without subtracting performance was shortening the hosel, which freed up discretionary weight to be placed on the perimeter. This means that the irons will have similar performance to the S3 Pro irons, but with a much better feel.
Because of the added mass behind the sweet spot, however, the AMP Cell Pro irons have a slightly lower MOI, which decreases forgiveness but gives golfers more ability to work the ball. For this reason, Cobra PGA Tour Staff players Rickie Fowler and Jonas Blixt are playing full muscleback sets of AMP Cell Pro irons, which provide an even softer feel and a lower MOI for more workability.
Think the full muscleback set is for you? You’re in luck. They’ll be available in the early spring (we’ll add a more specific date when we get it) through Cobra’s custom program. Both sets will retail for $899.
Before you pull the trigger on the same irons Fowler and Blixt are playing, consider this: the AMP Cell Pro Muscleback long irons have 14 grams less perimeter weighting than their dual cavity back equivalent, which will make off-center strikes fly shorter and more crooked. While you might dress like Fowler and Blixt, you probably don’t hit it like them. Choose the flow set to hit it pin high more often.
