Whether you have the older 4Runner or the more modern one it’s the kind of vehicle that deserves to be looked after because it can get you to almost any destination you can think of and it can get you there in comfort. That means that you need it to be running at its best and the easiest way to do this is to install the right performance upgrades so you’ve come to the right place because we have a range of them. Our Toyota 4Runner air intakes are a great place to start and they cost less than you would expect!
Your engine uses air and fuel to work and an aftermarket intake will improve your engine’s performance by giving it more air or colder air. There are different types of aftermarket intakes with different improvements like the short ram intake which allows a higher flow of air to reach your engine by removing restrictions or the cold air intake which will give your engine cooler air that can be burnt with less effort. Because we have them all it’s easy to find the right one to get the performance improvement that best suits your driving style!

- Performance Air Intake SystemsCan an Air Intake System also Increase My Fuel Economy?We all know that achieving better fuel economy while driving puts money back in your pocket and does the environment a favor. But for those who are actively interested in squeezing the most out of every drop of gas, getting more miles per gallon can actually become a sport - especially if a vehicle has a manual transmission that can be upshifted earlier and put into neutral during downhill grades or when coasting to a stop sign.
- Performance Air Intake SystemsThe Real Cost of Your Car’s Cheap Factory Air FilterIn today's world, saving money wherever possible has become essential. But it's important not to lose sight of the fact that, sometimes, a product that costs more up front will save you more money over time. In our business, we've seen far too many consumers judge products solely on the basis of their initial cost, completely neglecting any long-term economy and benefits. When it comes to automobiles, "performance" air filters are a perfect example of this.
- Performance Air Intake SystemsMy Car is Brand New | Why Should I Change My Air Intake System?Aftermarket air intake systems have become one of the most popular engine modifications available for late model cars and trucks. An easy question to ask is why are these so popular? After all, didn't engineers who work for your vehicle manufacturer spend years developing the best engine components available? Since power and fuel economy are major selling points these days, it's hard to imagine car companies not doing everything they can to maximize horsepower, miles per gallon, or both.
- Performance Air Intake SystemsWhat are the Different Types of Air Intake Systems?There are many types of aftermarket air intake systems that range from simple and inexpensive to elaborate. In the scope of this article, we'll examine the different types of air intakes, what they do, and look at a few specific product examples of each. But in short, performance air intake setups increase airflow into your engine - boosting combustion and creating more horsepower and torque that you can actually feel. Their relatively low cost and easy installation (bolt-on in most cases) keeps them in popular demand by car enthusiasts that own everything from 1.5-liter turbo motors to big block V8 engines.
- Replacement Air Intake PartsWhy Does My Car Have a Plastic Intake Manifold?An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a mounting point for carburetors, throttle body assemblies, fuel injectors, thermostats, and more depending on vehicle manufacturer engineering preferences. Intake manifolds may also serve to route coolant through dedicated channels in order to remove heat from the engine. Because of their location and functionality, intake manifold assemblies are under constant stress from engine vacuum pressure as well as direct heat from coolant, cylinder combustion gasses, and the cylinder heads to which they are mounted.
