Measure the inlet after the snorkel head is removed (most cases your inlet will be 3.5 inches or 4 inches).Remove the current head from your snorkel.potato-potato? -p depending on how you want to say it.

It's the Spin-Science applied across the design of the Dome and rotor that makes The Sy-Klone Series 9000 the market-leading engine Precleaner*! (or PreFilter*. Decades of field testing forged the range of different Series 9000 Precleaners and adaptations to perfectly match the environment and CFM requirements of each engine to maximize particle separation. In fact, it is the science we pride ourselves in. We have run the numbers on CFM consumptions across all types of engines. Not all engines are the same and you want to make sure your Precleaner fits your engine like Cinderella's slipper, perfect. This also includes diesel motors up to 3.5 liters in displacement. The 9001R has an inlet size of 4 inches This is for Gas Engines between 4.8 to 6.2 liters displacement size and can be super or turbocharged. Which has a CFM efficiency range of 275 CFM to 350 CFM. Order both the precleaner and an adapter together to receive discounted pricing! Fits virtually any snorkel using an adapter. I'm still looking at mine deciding which to use.The snorkel pre-cleaner is a patented technology that uses the centrifugal force generated by the rotor inside of its dome to separate particles out of the air before going into your snorkel, leading to much cleaner air for your engine. The reason I keep noting 2 sizes is that fitting a 3" elbow into the lower air filter housing runs you into the air filter where 2.5" does not.
If you run 2.5" you'll need a step-down adapter (3" id to 2.5" od at the snorkel body). This will require you to fit a 2.5" or 3" elbow to the lower air box to attach to. It's high temp, reinforced, waterproof and light. This is what's used on track cars to duct cool air to brakes. After some searching I'm using flexible brake duct hose which is available in 2.5" and 3.0" ID's. From there you can either run a 2.5" or 3" hose to your air box. You will have to clamp it from within the fender well, plenty of room though. Good news is the larger part of the snorkel before the step is right at 3" OD, an there's plenty of room to clamp a hose if you cut off the 2" step down part. At low RPM that's not a big deal, but no need introducing restriction into what is already an exceptionally long intake path. The throttle body on a 22RE is about 2.5", the inlet on the air box is 2.5", but the necked down portion of the snorkel where it enters the engine bay is about 2 inches, 20% smaller. Since these snorkels are for low revving diesels, they're sized too small for higher revving gas engines. On my truck, 1/4" would have been even better.

The 3 stud holes also need to move 1/8", but straight back, not up. 4Runner 5th Gen TJM Snorkel 475 (bou > Broomfield ) pic hide this posting restore restore this posting. The inner fender hole (on the engine bay side) needs to follow the outer fender hole. That's why everyone has to trim the hole further after drilling. The main hole in the fender should be centered about 1/8" up and to the rear when looking at the fender (ie: 2:00). First, the template provided is a little off. Just finished installing mine so it's fresh on my mind. I thought I'd tack something on this older post as it still comes up in searches and is pretty thorough.
