PRL's titanium inlet opens that path up dramatically, taking the compressor inlet from the factory 38mm to 45mm and running 74mm ID through the crossover. Thin-wall titanium keeps heat out of the charge, and the whole thing bolts on with no tune required.\u003c\/p\u003e\n\n\u003ch4\u003eRead This First: You Need A PRL Intake\u003c\/h4\u003e\n\n\u003cp\u003eMost important thing on this page. This inlet pipe \u003cstrong\u003eonly works with PRL's Cobra Cold Air Intake or Short Ram Intake.\u003c\/strong\u003e It does \u003cstrong\u003enot\u003c\/strong\u003e fit the stock airbox, and it won't pair with another brand's intake either.\u003c\/p\u003e\n\n\u003cp\u003eSo if you're still running the factory intake, this isn't a standalone upgrade. You need the PRL intake first, then this. If you've already got the Cobra or the Short Ram on the car, you're exactly who this was built for and it's the natural next step.\u003c\/p\u003e\n\n\u003cp\u003eWorth being blunt about it because it's the kind of thing that gets discovered with the bumper apart.\u003c\/p\u003e\n\n\u003ch4\u003eWhy The Inlet Side Matters\u003c\/h4\u003e\n\n\u003cp\u003eEveryone thinks about what happens after the turbo, the charge pipes, the intercooler, the exhaust. The inlet side gets ignored, and it shouldn't.\u003c\/p\u003e\n\n\u003cp\u003eYour turbo can only compress what it can draw in. Restrict the path feeding the compressor and the turbo works harder for less, which shows up as slower spool and less airflow at the top. The factory inlet is sized for a stock car and becomes a genuine limitation the moment you add boost or open up the intake ahead of it.\u003c\/p\u003e\n\n\u003cp\u003ePRL's numbers tell the story. The compressor inlet goes from 38mm to \u003cstrong\u003e45mm\u003c\/strong\u003e, and the crossover pipe runs 76.2mm OD and 74mm ID. That's a significant increase in volume, and it's sized deliberately for a 1.5 liter engine rather than just made as large as possible, so you keep velocity instead of trading it away for a bigger number.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Titanium\u003c\/h4\u003e\n\n\u003cp\u003eTwo reasons, and heat is the bigger one.\u003c\/p\u003e\n\n\u003cp\u003eThin-wall titanium is a poor conductor compared to aluminum, so it soaks up far less engine bay heat and passes less of it into the air heading for your turbo. Cooler air in means denser air in, which is the whole game on a forced induction car. On a small turbo motor working hard, heat soak in the inlet path is a real and often invisible loss.\u003c\/p\u003e\n\n\u003cp\u003eThe second reason is that it looks the part. Titanium in a bay is the kind of detail people notice, and on a car where the inlet is visible, that's not nothing.\u003c\/p\u003e\n\n\u003ch4\u003eCast Aluminum Inlet Piece\u003c\/h4\u003e\n\n\u003cp\u003eThe pipe meets the turbo through a cast aluminum inlet that's gasket-matched to the 50mm ID compressor inlet, then transitions smoothly out to the 76.2mm titanium crossover. That transition is where a lot of inlet designs lose their gains, because an abrupt step creates turbulence exactly where you want smooth flow. Casting it lets PRL shape the transition properly rather than working with what tube stock allows.\u003c\/p\u003e\n\n\u003ch4\u003eMulti-Piece Design Makes Install Easier\u003c\/h4\u003e\n\n\u003cp\u003eA one-piece inlet sounds better on paper and is worse in practice. PRL built this in multiple pieces specifically so it fits better and installs more easily, since you're working in a tight space and a single rigid piece has to thread past everything at once.\u003c\/p\u003e\n\n\u003cp\u003eYou get high-temp 4-ply silicone couplers and 304 stainless interlocking worm clamps to tie it together, so the joints seal properly and nothing rusts on you.\u003c\/p\u003e\n\n\u003ch4\u003eWhat's In The Kit\u003c\/h4\u003e\n\n\u003cul\u003e\n    \u003cli\u003e(1) Cast aluminum inlet piece\u003c\/li\u003e\n    \u003cli\u003e(1) 76mm OD titanium inlet pipe\u003c\/li\u003e\n    \u003cli\u003e(2) High-temp 4-ply silicone couplers\u003c\/li\u003e\n    \u003cli\u003e(5) 304 stainless steel interlocking worm clamps\u003c\/li\u003e\n    \u003cli\u003e(4) Vacuum hoses\u003c\/li\u003e\n    \u003cli\u003e(1) Injection molded evap purge fitting\u003c\/li\u003e\n    \u003cli\u003e(2) Buna O-rings\u003c\/li\u003e\n    \u003cli\u003e(1) Bolt\u003c\/li\u003e\n    \u003cli\u003e(1) Wiring harness tie-down\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eEverything needed to complete the install, including the vacuum and evap plumbing that comes off the factory inlet.
