Skunk2 Racing 307-05-0260 Pro Series Silver Intake Manifold for Honda D-Series Engines

Bolted straight onto my D16Y8, no clearance issues etc. Looks beautiful.

I recently had the pleasure of installing this on my D15 Honda Del Sol.THIS IS A PERFORMANCE PART, NOT YOUR STANDARD OEM REPLACEMENT. PLEASE READ.To start, this is a FANTASTIC performance application for your Honda build. It is a MASSIVE intake manifold in comparisson to the factory application, offering a dramatically increased flow rate, one of the key parts to performance. Mine is paired up with the 70mm Alpha Series Throttle body, and I recommend this. Throttle response is immediate, and the increase in power is substantial . Anyone serious about building a true performance Honda, this is the way to go. (It will set you apart from the "ricer")Overall, without a dyno tune yet (and some other modifications) I am looking at a 30%+ power increase. Granted this is by no means my ONLY upgrade, but I would contribute a large piece to this.Some people are more worried about sound (which doesn't make much sense to me) but for those of you out there, this gives you a deep throaty tone, and accents your engine noise. This will also carry through to deepen your exhaust tone, for those of you worried about that.I am a mechanic, one who has been in the high performance realm for some time. Whenever you buy something of this nature, even if it is "made for your car" some fabricating has to be done. I just want to give anyone who is buying this a heads up before getting frustrated after purchasing.-Some things for my application that had to be modified for fitment -MAP Sensor is relocated, and will need some wiring added to make it to it's new location. It will also need shaped (Carefully) with a dremmel to fit into it's new location. - The Throttle Cable Bracket will need to be reversed, as it is relocated an inch left on this part. - There are no gaskets included, I recommend buying an Intake, Fuel Injector O Rings, and Throttle Gasket - You will need some 1/8" bore vacuum line for the EGR Valve Vacuum Line being relocated (13") and you will need T offs for the Fuel pressure regulator Vacuum line, and the Return Coolant line from the Throttle Plate. - The original hose clamp for the Intake Coolant return line will not work, as it is a clamp style to large to fit in the smaller gap between intake and manifold. You will need to get the traditional tighten-by-screw hose clamp.

Installation was pretty straightforward. I had previously rerouted my coolant lines from my throttle body and such, so I did minimal rerouting here. Paired with the Alpha Series 70mm throttle body, these were a significant upgrade over stock. A few minor modifications needed, nothing major: pcv was not necessarily relocated, but now kinda suspended in limbo, throttle cable bracket needed modification, and IAT sensor needed to be relocated. The IAT bung on the manifold was a bit small for the sensor so I plugged the bung with a short screw and relocated my sensor to my intake piping just before my throttle body. All other components; fuel rail, injectors, etc were a direct swap. (95 EG sedan).The manifold port is also a tad smaller than the throttle body and would benefit from a quick port match; shave down about 2mm and done. Noticeable difference off the bat in mid range and top end, better throttle response as well. I will be tuning it all up with Neptune before too long. This combined with complete header-back exhaust and cold air intake, I would guess about 20 horses have been added.

I ordered this model through an ebay seller originally and a coolant passage blew off the back. No problems with the one that I bought here on Amazon though! Prime shipping is also a +. Easy to install and definitely adds to driver experience. At WOT it sounds similar to my 9th gen si!

Love it best upgrade yet it's a must have I paired it with the skunk2 70mm throttle body an man did it open up my motor
