Hi, I’ve owned an 1987 RX7 from the factory with USA specs. 80k on car and in need of new radiator. Most replacements on internet show cap on top, this will interfere wi5h air duct. Looking for suggestions?
Thanks!

The cap on top does not interfere with the air inlet duct. It can be tight at times but it will be just fine.

Great info about the fitment. On a related note, I have seen with the koyo rad for an s4 you can’t get the n flow or the rad that forces the coolant to double pass or whatever. They only make the N flow model a direct drop in for the s5. Is the s4 koyo rad still a ton better than stock and that should be sufficient? Or is it worth the extra hassle to buy the n flow koyo for an s5 and figure out how to adjust the brackets to mount into the s4. Sorry don’t mean to highjack the thread but sort of related . Any input?

recently upgraded from a fluidyne radiator to a koyo n flow for my t2 and it made a big difference, so I’m a believer in the double pass technology.
