it is not necessary for your fuel economy to go up unless you are putting some hardcore engine mod like a turbo etc.
a simple intake/header/catback will give you some gain without breaking the bank. dont expect too much though...the d16 motor is meant more for economy so it is not very responsive. [/highlight]
I beg to differ, by installing Intake/headers/exhaust(be catback or non) what do you think will happen? You are actually improving engine efficiency by allowing the engine to breath better. Meaning more air is able to go in the combustion chamber then normally, and more is being pushed out. So what do you think the ECU would do (more specifically in a Honda D16)?
I call these new ECUs the learners, they learn your driving habits and the evaluate engine air/fuel flows all the time and control engine so. So by doing the above mentioned mods, if you do not expect to increase fuel consumption, then my friend you are incorrect. You will increase fuel consumption but not to the extent of blowing up your life savings. And Honda D series engines are more responsive to such mods then the B-series due to more restriction in the D-series in the intake, and exhaust.
and i will not suggest iridium or platinum plugs since they are not recommended for low compression and non-high performance motors generally. there will be no added advantage...do your research on the plugs part...you will know.
Again we are not on the same wavelength, Turbo engines are low compression engines with ratio of close to 8:1 and D-series has CR of 9.3:1-9.5:1. So they are not considered low compression.
