Can I put a 4 cylinder cold air intake into a 6 cylinder?

I have a 2002 honda accord v6… I got a cold air intake for a v4 civic… Will it make a difference if I put it in my v6?

Cold air intake systems only really make a difference at high RPMs. Under normal driving you will see almost no difference in power or mpg. You will never recoup the money spent on fuel saved. The system will have to match the engine. Be it a V6 or Inline 4.

Yes. V-6 cold air intake on a V-6 does almost nothing except empty your wallet. V-4 cold air intake on a V-6 restricts air flow to reduce performance and empties your wallet.

Install it and see what happens…

Wow, you had a V-4 engine? Cool. Waste of money, unless yer makin' 350+ HP.
