ok. I'll buy the cone filter and measure it. if it's got less surface area than the drop in, you can pay for it.
(IMO cone packaging is popular because it's universal fitment, and the internet's obsession with "cold air intakes" that are often actually "hot air intakes"). |

"To find out how manufacturers reach the best compromise between these often contradicting needs, we consulted with Trent McGee of Airaid. Here’s what we learned....“Open-element cone filters are very popular in aftermarket air induction systems because they provide a drastic increase in surface area over a flat-panel filter. The greater the surface area of the filter, the more air an engine can ingest,” McGee says. “Even when we’re limited in space by the design of the airbox, we still try to increase the filter’s surface area as much as possible by increasing the number and the depth of the pleats. In addition to improving airflow, the larger filtration surface improves the longevity of the filter as well.” Pretty sure I read the same on K&N's website as well, which I could dig up. You're literally arguing with me over something that may changes the numbers a fracton of a horsepower. It's not that serious. |

I mean not all cars have the same size stock flat-panel filter and not all cone filters are of the same size. Our stock intake has a reasonable size stock filter and it's designed to take advantage of the full area... Again not saying that it flows better a flat panel versus cone, it's just that in this case the size of the smaller cone filter could actually have less surface than the stock flat-panel that's of a reasonable size. Btw. I'm just asking, as nobody actually tested this I don't think we can just assume, but I'm curious, as personally I would like to do this mod, I just want to make sure I don't lose power but gain, even if it's 0.1111111hp I care mentally lol.

True- Not sure what I was thinking there For others that have done the 1/2 Dinan- what are you guys doing to mount the hose by the fog? or is it stiff enough to stay there..? What are you doing to get air through the closed grill?- Drill or open mesh grill |

I have both the Dinan Ram Air and the air scoops, plus I'm running an AFE dry element air filter, the charcoal delete, and the silicon intake tube; and I can tell you at speed, above 60 MPH, there is a noticeable difference in power.

While the Dinan ram air came with a new grill I couldn't use it because it didn't have the little wing, so I drilled holes then opened them up even more with a Dremel tool. Per the attached picture it's the right side of the grill, both top and bottom I opened up. The Dinan ram air system comes with an air scope that mounts behind that portion of the grill that transitions into a tube that feeds air into the air intake. Of course, the Dinan badge is probably worth two or three horsepower!

Dinan kit is rare, and the scoops are cheaper

I have the scoops but decided against the ram air mod due to hydrolock concerns. No significant increase to horsepower that I can tell, but I have noticed an efficiency increase of ~1 mpg after the install.

Since I have the Dinan ram air and we have had a significant amount of rain that resulted in me having to drive on flooded streets, I initially had the concern about hydrolocking. But as I thought about it and remembered I have two sources of air intake so there was no way there was ever going to be enough vacuum in the air intake system to draw water into the air intake through the Dinan vent.

Suck some water up the the intake port that is really close to the ground?
Tom Droze makes a good point about having dual inputs for the intake so vacuum *shouldn't* be a problem, but Murphy hates me and if it can happen it will happen to me. I decided it was one of those mods that would give negligible gains for my purposes (spirited DD) while potentially increasing the risk of damage, so I just didn't do it. EDIT: Also running a Eurobox that I plan on removing when I sell the car, didn't want to chop it all up and be unable to sell it later. |

Anyhow, sell the EU now and use the money to buy a Dinan. |

No thanks. The convenience of changing air filters in the Euro-box vs. the US-box outweighs the minute gains I would see from the Dinan mod.

A local guys Euro mod using Honda intake, yes its dirty his car is a super daily driver & bulletproof weekend racer
He even has the Intake elbow like the Rev Motoring pipe basically he did what is described here around the Maf, but i think his pipe is a smaller diameter to TB than oem... Idea credit to @mikal7

It's an ITG intake. Main reason for me is that it makes a lot of noise which helps because this car is ultra quiet which sucks on track. I don't like exhausts and honestly this car doesn't need one. I do want some of those supersprint headers but $$
The sound is great though. |

Use a drill and drill holes close together as a template but smaller than the actual hole you need. Then cut it out with wire cutters or a sharp knife. Then use a Dremel tool to shape the hole to the size you want it.
