now i wanna know the dyno for the Injen CAI with AC on. That's a significant difference. :thumb: I meant to do it last night but got sidetracked with a less-fortunate member. My theory is that the drive-by-wire system in the Civic, intended to give the impression of more power to the user, opens the throttle further than you think you are opening it when you press the throttle to accelerate. what i would do is next time it rains really hard check your engine bay and see how wet it is after youve drive for awhile, and through some puddles.pretty impressive makes u wonder if a CAI is worth all the extra money....the hydrosheild also acts as a prefilter.

That being said, it's not that the Lexus has such a better intake as it could very well be that the Civic needs more throttle opening to achieve a similar cruse speed and that's accounting for the difference. As an added bonus, the upgrade should be completely reversible, and nearly completely stealth.We'll explore some of these options and do some before/after testing in the next article. Granted, it's an automatic, but we did measure the acceleration time AFTER the car had downshifted (so that time doesn't take into account the actual downshift). General Discussion (8G) Type-R … We've talked a little about this in a previous articleI do not have a vacuum gauge as I do a lot of this sort of testing and I find that a digital differential pressure meter is better for my purposes.
I now feel that my car has more power than when I took my intake resonator off... and it sounds a lot deeper.

The only way to find out of course is to do some experiments.What I suspect without any further information is that while the IS300 takes advantage of the positive air pressure available to it by taking it's air from just above the radiator via a forward facing intake snorkel, the Civic is actually taking air in from a shielded location, a location that also happens to be rather warm.At most speeds, the Civic doesn't take advantage of that free potential horsepower (and actually a theoretical gain in gas mileage too - thanks to a reduction in pumping losses, but more on that in another article). If you want to squeeze more power from your Honda Civic, upgrading to a performance intake manifold will provide a sure path to power gains, no matter the size or configuration of your engine.

U make me feel bad for spending so much for a Injen CAI. From United States; DC Sports Cold Air Intake System Fits 06-11 Honda Civic DX LX EX CAI5525 . It means there's not much room for improvement in the stock intake and it's quite good. I then connected my vacuum hose to the intake arm and ran the vacuum hose into the cabin to my differential pressure meter. Vehicle finder tool ...

No vanes in the r18. I was however able to duplicate a pressure drop of -7.8 inches of water.Project Lexus' original intake measurements were -9.1 inches of water but after we fixed the hood seal that was blocking the intake's snorkel a bit, we saw a measurement of just over -8.0 inches of water. :thumb: I meant to do it last night but got sidetracked with a less-fortunate member. 31 Sold. Induction . Home Forums > Civic Technical > Bolt-Ons And All Motor > Intakes & TB Spacers > New r18 intake?

Today we're going to look at the 8th generation civic, specifically the R18 powered Ex model. Your automobile's air intake system consists of many parts, including the intake manifold that has a series of tubes to distribute the air equally to each of the cylinders. This can be a little frustrating when trying to quickly overtake someone on the highway. Greece Any non Civic chat here please! The R18 as you probably know is a 140hp power plant that is extremely fuel efficient but lacks some sense of urgency, especially when overtaking on the highway. The IS300's intake we said was VERY good, so the -7.8 measurement we're seeing on this Civic is a double edge sword. r18 intake manifold. The ECU will target stoichiometric 100% of the time. This intake manifold features CNC velocity stacks, CNC machined flanges, and is made in-house to ensure top quality.
