Getting ready to start upgrading my '03 4.6L; nothing radical, just looking for a little more snap and mpgs. Starting with air intake/TB spacer and cat back system before moving on to UD pulleys and electric fan(s) and somewhere in there a chip.
I ride Harleys and build my engines so tools and mechanical skills are OK. My problem is evaluating the myriad of products for the above upgrades; which are quality and deliver? I think it foolish to go start buying stuff before checking in here. Most driving is in town, hit the highway for some short trips to the coast and tow a trailer with a Harley on occassion. Looking for torque first, horsepower second. Don't want loud exhaust, don't want a resonating hum in the cab.
Looking at air intakes, TBs and exhaust first and have narrowed air intakes down to K&N CAI 77-2514KP or AEM Brute Force with Jet Flow TB spacer and Flowmaster or Magnaflow cat back system.
Looking for recommendations for/against any of the above from people that have used them and know what they are talking about. Also would like input on the value of replacing the stock CAT with a free flowing unit.
