INT-FWI-xxx - INTENSE™ Fenderwell Intake Kit
Should only need your basic hand tools, nothing special I can think of.
IMH-340 - INTENSE™ Modular Pulley System with 3.40" Pulley GB6-660
Pulley Puller (I'm not sure about other tools though)
GB6-715 - Goodyear Gatorback Supercharger Belt
T-50 Torx bit for the tensioner (rotate the wrench toward the firewall to relieve tension)
TST-180 - INTENSE™ High Performance 180 Degree Thermostat
I use a 10mm deep socket to get to the bolts on the housing more easily. Gasket and o-ring? I'd maybe suggest getting a small section of clear tubing from the hardware store, and old gallon jug, and siphoning out about 1/3-1/2 gallon of coolant from the radiator. Read the coolant fill proceedure in techinfo too.
ASP-605 x 6 - Autolite® 605Copper Core Spark Plugs
5/8" Spark Plug Socket and some various extensions. I've found it'* good to have a nice mix, maybe even a swivel. Dielectric grease for the plug/wire connections. You may want to consider a set of Napa Belden wires to go with depending on the age of your current wires. Those actually come with a tiny packet of the grease, but I'd suggest getting a bigger tube for future use.
INTENSE™ Standard Powertrain Control Module
Check to make sure you have the right size socket for the bolts that attach the PCM wiring harness.
I'm sure others may have more to add.
