Ok so, i purchased one of this on ebay for around 20 bucks, i said eh whats 20 bucks right. Now i want to know opinions and facts from you Honda experts! Is this a good piece of equipment to save gas or is it more for performance?

 

JDM= Japanese Domestic Market, meaning is what something sold regularly only in Japan.

I highly doubt, you have a genuine product. An adjustable regulator for any car, not just Honda's is designed to raise of lower you fuel pressure needs as you modify your car with more serious parts to keep the air/fuel mixtures correct. Any type of research would tell you that

 

Looks good to me OP. Use it.

 

Its for adjusting fuel pressure for engines that have been modified. For a stock engine its for looks alone.

 

I have a set of jdm fogs with dirt. How much is this jdm dirt worth?
