Review on DNA Motoring OEM-ITM-004 Intake Manifold 615-188: Upgraded Performance for Ford F150/F250 F350 SD 5.4L V8 by James Martin

processed cheaply. You can bend the plastic at the bottom just by pressing with your fingers. The way they welded the top to the bottom has big gaps in between. Self-tapping screws are a time bomb for solving road problems. The hex on top of the self-tapping screws used to hold the coil packs has a small surface and is rounded on top, making it difficult to grip the socket. The throttle body bolts were difficult to install, I even tightened them to the hilt. Too bad it's made in the USA. I always get non-OEM (although they say this distributor is OEM) but I'm sorry I took my luck on this part. My friend told me he negotiated with a Ford dealer and got $100 off his motorcycle intake manifold. It's a shame I went this route.
