Ive had my 4runner for over a year now, but its just lacking power the cars still completely stock no mods done to it. i was wondering what kind of mods i should start out with and which would be the best??

Search around a bit, you'll find lots of info. Start out with free flowing intake/exhaust.

Well, first off you should describe your rig a bit more--is it a 4 or V6, auto or manual. If you have a V6, the one mod that research has proven to be the most beneficial is headers--they eliminate that absurd bottle-neck of a crossover pipe, and make it possible for any other mods to reach their full potential. Remember, an engine is nothing more than an air pump, and if you can't get the gases out quickly, you can't put more in. The added benefit is you eliminate that hot spot behind the heads that causes the head gaskets to fry.

If you have a V6 auto, you never had power to begin with, just an FYI.

Here's a list I posted in another thread.

Ok, here's the list:

Check with dealer and see if head gasket recall was ever done. If not, they should still honor that.

Plugs (NGK) and Wires (Denso), brand does matter. Change cap and rotor and check the timing.

Air and fuel filter. You may have issues with the fuel filter. Spray the nuts on each side daily with PB Blaster every day for a week before you try removing it.

O2 sensor and general exhaust inspection.

Drain, flush and fill your coolant and transmission fluid.

Change the oil in your differentials.

Check the boots on you CV axles. If damaged, swap them out for new ones.

Sounds like you're only interested in light wheeling, but a solid set of all terrain tires is never a bad thing. BF Goodrich AT's are great and affordable.

After all that, it should run great. Now, how insane do you want to get? There is a plethora of offroad extras you can add.

What kind of headers do you rec. Bucknut?

What kind of headers do you rec. Bucknut?

Northwest Offroad makes some really nice ones--the guy who runs things is a bit odd, but their equipment is solid. Doug Thorley makes some as well. There are one or two other places that sell them--maybe someone else can chime in. Be warned, they're all pretty pricey--I'm guessing it's not a high volume item. It you go single exhaust, which is likely given the tight quarters under the truck, you will also need a proper Y-pipe to mate the headers underneath.

Look up 7mge AFM swap. There are a few people over on yotatech that say it really wakes up the engine. I have the AFM sitting in my garage, just haven't had the time to do it yet. That's if you have the V6, of course.

He needs to describe the truck a little more first...

Are you running over-sized tires?
