melena 2 - '98 civic hx
Thanks: 0
Thanked 0 Times in 0 Posts
new from mexico. Honda civic HX 98

my name is albert, im mexican.
a week ago I bought a Civic 98 hx with 134xxx miles.
since long time i was looking for a civic VX but i dont found anything, so my other options was a toyota echo 2001 and this civic (same price both).
I choosed the Civic because my brother bought a toyota echo and the parts of these car are very expensive comparing to the Civic, like the clutch set, brakepads, struts and shocks. And the best part... the aftermarket


The Civic comes with an AEM intake , sometime ago I read that the aftermarket intake (like my aem intake) helps in the fuel efficiency. Its that true?

Versions of this question come up often. Search this site regarding air intakes and fuel economy and you'll find a bunch of answers to it. But to save you time... the answer to your question is "no." I have a very similar car to your 1998 HX (a 1998 DX). I was able to show that a so-called "warm air intake" helps FE on my DX, but your HX has lean burn and EGR features mine does not. You could test. Check my car's entry in the "garage" section of this site. You might find ideas there that you would like to try on you Civic. -james

I held out so long for an HX or VX to come up on the market, but I ended up settling with the LX.

I would also say no to the intake. For high-RPM grunt, sure, it will improve HP slightly. But for fuel efficiency, I'm pretty sure the rule is "warm is better" such as a short ram or a warm air intake.
