Two 1\/8\" NPT ports take methanol injection or a boost sensor (plugs included), and it clears the engine cover.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e60 mm lower and 76 mm upper pipes, mandrel-bent aluminum\u003c\/li\u003e\n\u003cli\u003eCNC-machined 6063 aluminum ends with 3 mm wall\u003c\/li\u003e\n\u003cli\u003eAramid-reinforced three-hump silicone joining hose\u003c\/li\u003e\n\u003cli\u003eFlow: 558 CFM vs 439 CFM OEM at 150 mbar — 27 percent more (do88 testing)\u003c\/li\u003e\n\u003cli\u003eTwo 1\/8\" NPT ports for methanol injection or boost sensor, plugs included\u003c\/li\u003e\n\u003cli\u003eMikalor hose clamps with inner rings\u003c\/li\u003e\n\u003cli\u003eBlack powder coat; clears the engine cover\u003c\/li\u003e\n\u003cli\u003eReplaces OE 13718651066\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2 × do88 charge pipes (upper and lower)\u003c\/li\u003e\n\u003cli\u003e1 × do88 silicone joining hose\u003c\/li\u003e\n\u003cli\u003e2 × hose clamps with inner ring\u003c\/li\u003e\n\u003cli\u003e1 × M6×16 screw\u003c\/li\u003e\n\u003cli\u003e2 × 1\/8\" NPT plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extras:\u003c\/strong\u003e none — the OE seals, turbo-outlet clip and sensors transfer to the do88 pipes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation instructions (do88):\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/do88-TR-390-installation-instructions.pdf\"\u003eTR-390 GR Supra \/ Z4 M40i charge pipe installation instructions (PDF)\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation notes:\u003c\/strong\u003e remove the airbox and engine cover, disconnect the sensors and remove the inlet pipe and OE charge pipe.
