Hi guys,
There is no problem for these to clear. This is of course referencing our kit. We recommend the recessed mounting posistion to better support the oil cooler, while not putting as much strain on the composite core support.
We have actually had the Stillen Gen 3's installed on our car with the oil cooler in the forward posistion, and a nismo front body brace (we did have to shim the mounting of the nismo front body brace to clear our AN fittings on the core, but it all fit).
There is no additional modification or deviation from our standard install to allow Stillen Gen 3 intakes.
I hope this helps.
