This has only been used once on my car, I have a mk2.5 1.8vvt and it was a very tight fit next to the pcv valve which was not suitable for my car.
I definitely know that it was a tight fit on a 1.8vvt but from what I have seen this is perfect for the other style mx5s. Description below about product.
