PE ones are a little cheaper than the Nismo versions, but heres the other option.
Z32 guys don’t trust them for our cars, but SR and KA guys stand by them as an amazing product.
What do you think about DeatschWerks?
From what I understand they are OEM refurbished injectors that are drilled out to have higher flow capabilities.
All of them are flow tested and their tolerances are extremely tight.
