I would be careful with My Spark Disappeared coils. Ive had a few of them fail over the years with very low mileage. The OEM coils are the best coils out there for them AFAIK. If youre still running the stock cams, thats a place you can pick up some power but you have 4 of them so its expensive and you will need a tune after changing them. If you do cams, a throttle body may be a good investment too but I wouldnt change the TB without cams. With all of that said, a blower or turbo would be one of best investments you can make regarding money invested vs power gained. A set of cams is about half the price of a blower kit.

Cams, baby. Cams. 4v can return major gains with better cams. Factory cams are not exceptional. Will need to do springs with any cam worth doing. Lots of cam with a 4v will reduce low rpm power but with IMRC plates still in the mix you'll probably have the best of both worlds. If you put fat cams in it you'll probably start running at the limit of or exceeding the capacity of your 24# injectors so you will likely need to go to 30's or slightly higher. My 02 v4 swapped GT needs more injector and it's pushing 330rwhp on 24's.

So your suggesting
1. OG Coil Pack's
2. MHS 4.6L 4V Stage 2 N/A Camshafts
3. Throttle Body.
4. 30+LB's Fuel Injectors
Cherry On Top.... TUNE!

Throttle body would only be needed if you're seeing a restriction at high rpm. It may or may not be needed. The stock throttle body is 57mm. I don't know if better cams are going to flow enough to see a restriction. If your going to buy injectors, i would recommend Siemens deka4 80s. They are the same price as other injectors but you are likely to never outgrow them, even if you decide to add forced induction.

I mean in Actuality though are we EVER TRULY done building our cars? No, Hell No..not even close. I'm always adding Performance/Non-Performance parts lol.
This is just another addiction that has no big consequences & Smiles-Per-Gallon is a real thing! :D
