This HPD breather is engineered to fit both 4JJ1-TC (2007-2019) and 4JJ3-TCX (2020+) engines.

That's exactly what this breather is designed for. The top-exit design makes routing to a catch can much cleaner and more compact.

You can also use alternative hose connections depending on your catch can setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What size hose does this take?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The top-exit outlet is designed to work with the HPD -10AN push-in adapter, which accommodates -10AN braided hose (common catch can plumbing size). Without the adapter, you can use appropriate sized rubber or silicone hose with hose clamps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I vent this to atmosphere instead of a catch can?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Technically yes, but we don't recommend it. Venting crankcase gases directly to atmosphere releases oil mist and potentially harmful vapors. A catch can is the proper solution for capturing oil vapor while allowing clean air to vent.\u003c\/p\u003e\n\u003ch3\u003eInstallation \u0026amp; Hardware\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is hardware included?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No. Mounting screws for 4JJ3 installations (4 × 8G \/ 4.2 × 16 mm stainless steel) are not included. You'll need to source these separately from hardware suppliers or order them when purchasing the breather.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Where can I get the screws for 4JJ3?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Any hardware store or fastener supplier should stock 8-gauge (4.2 × 16 mm) stainless steel screws. Make sure they're stainless steel for corrosion resistance in the engine bay environment. Alternatively, contact us and we may be able to include them with your order.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What tools do I need for installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Basic hand tools — typically a Phillips or hex driver depending on your screw choice. Thread locker is recommended. Total installation time is 15-30 minutes for most DIYers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I install this myself?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: If you're comfortable with basic mechanical work, yes. It's a straightforward removal of the factory breather and installation of the HPD unit. Ensure all connections are tight and properly sealed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to drain coolant or remove other components?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No — this is a simple bolt-in replacement for the factory crankcase breather. No coolant draining or major component removal required.\u003c\/p\u003e\n\u003ch3\u003eDesign \u0026amp; Function\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why would I want a top-exit breather?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Top-exit design allows cleaner routing in tight engine bays, easier catch can integration, and better clearance from exhaust manifolds. It also provides a more professional appearance compared to factory side-exit breathers with messy hose routing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What's the advantage over the factory breather?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The HPD breather offers superior construction (CNC alloy vs plastic), cleaner routing options, better integration with catch can setups, and premium appearance. It's also more durable and heat-resistant than factory plastic breathers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this improve performance?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The breather itself doesn't add power — its primary benefit is improved crankcase ventilation routing and catch can integration. Proper crankcase ventilation (especially with a catch can) can help maintain engine cleanliness and potentially improve longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the alloy breather better than plastic factory unit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. CNC-machined alloy is significantly more durable, heat-resistant, and visually appealing than factory plastic breathers. It won't crack, warp, or degrade from engine heat over time.\u003c\/p\u003e\n\u003ch3\u003eProduct Quality \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this genuine HPD?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes!
