Good quality
Must have if you are replacing any upper or lower intake parts on a 2001 f150 with a 4.2 liter engine.

OEM quality at a good price!
If you have the notorious lean code issues on both banks of your 4.2 liter Ford truck and your o2 sensors are switching properly on the live Scan tool readings then these are what you need. Make sure you grab new manifold gaskets as well to replace them while you're in there. Dorman products always work good for me and they'll most likely do you right as well! I just wish they would include some paperwork displaying the proper torque for people less experienced, but I suppose Google works too lol

2001 Ford Taurus V6 DOHC
Amazingly, you cannot find these at local Autoparts stores...at least we can't where I live and they will not even order them. Thankfully, Amazon had them. We used them on the upper intake manifold of my son's 2001 Ford Taurus with the DOHC V6 when he dropped one of the original ones down into the engine compartment (not into the engine itself) and we could not find it. They are specified for use in the Windstar on many sites and even on Amazon it states they will not fit the Taurus (see picture). They fit perfectly though they look a little different. The rubber part is green vs black of the OEM and the bolt is a white metal vs brass of the OEM, but they worked! Hope this was helpful. If it was, feel free to click the “Helpful” button below!

Much improved
These bolts worked well on my 2009 Explorer intake manifold. They have 8mm heads and not the T30 heads so they won't rust and strip.

Worked like a charm
My windstar engine overheated and warped the heads, so I replaced them and was hoping the gaskets in the headset would fix the P0171 and P0174 codes and finally turn the light off. Nope. It was these stupid bolts that needed to be replaced as well. I appreciate all the comments here locating the actual problem. Thank you guys :)

Fits the 2003 Ford 4.0L Ranger XLT
Much better than the OEM T30 driver heads. This used a hex head on the bolts. Overall dimensions are the same as the OEM bolts. In the fitment it said it was not for the 4.0L engine, but it is a perfect fit.

seems to have served is purpose quite well.

Se los instale a una Ford Windstar 2001 desde enero y hasta la fecha no me han dado problema, la calidad es un poco inferior a la original pero funcionan bien en este modelo, son como aparecen en la descripción aunque la goma es de color verde claro, definitivamente los volvería a comprar
