The MAF conversion is finally complete. The throttle response is much better and drivability also improved. I am very happy with the results, and the installation of the Fiveology Racing MAF kit went smooth without any issues. The kit comes complete with all you need minus the throttle body and EGR spacer. Since I was wanting to use my stock air box with the kit I needed to purchase a 3.5" silcone coupler and clamps or I could have just bought conical filter with a 3.5" inner diameter and clamp to mount onto the 73mm MAF meter housing.
I upgraded to HoseTechniques silicone couplers and stainless T-bolt clamps. Visually they look much better than what was provided in the kit. They are high quality pieces and if you want the best then spending a little more is worth it in the end.
To make the short ram tube from Fiveology Racing work with the stock air box we trimmed the length down by about two inches. Remember always to measure twice, cut once! We also decided to polish the tube up a little so that it has a finish close to that of the polished throttle body and EGR spacer.
Besides much improved throttle response I notice more power from the car as a result of bolting up the larger 70mm throttle body and EGR Spacer. Of course with more air flow more fuel is needed and the 24 lb. injectors are up for the task. The wiring was straight forward and that task was handled by John Scatterday of Scatts Automotive.
All in all the Fiveology Racing MAF kit is the best way to go if you're thinking about converting your speed density equipped '86-'88 5.0 Mustang to mass air flow. In addition, you can custom taylor your MAF kit from Fiveology Racing according to your needs.
