Not to knock FAS, so please don’t take it this way.
The FAS is just a 6% pulley, same as the incognito etc. so power and performance will be the same.
The difference between one over the other is fit and finish. The belt rib fitment for example.
So at the end of the day, people looking for performance or ecu safety reviews, any review for an incognito will be the same.
But so far from what I can see, the fit and finish of the FAS is better. No squeal etc from a better designed, more accurate design and machining…
Ugh… maybe.., maybe after I recover the savings account from paying kids tuition and orthodontics.
