a friend asked me about this and I didnt know, He wants to get a JR header, but is wondering since he has the stock intake will the header heat the stock airbox and possibly melt it? They are really close and the stock header has a heat shield on it.

I told him it would probally be okay because when your moving there will be enough air to cool it even if there was a problem.

 

no, i notcied no difference in underhood temps when i had my JR header. If he's worried get some heat shielding material and wrap the box.

 

haha good, so im guessing it didnt melt your stock airbox

 

i was using a cone filter, didnt melt that. more heat with turbo.

 

Get a trackdogracing.com heat shield.

 

I've got a Racing Beat header and custom heatshield for sale in the classifieds here: https://www.miataturbo.net/forums/showthread.php?t=6094

I'll make him a great deal shipped to TN. Underhood temps are lower than stock.
