ive only suggested the drilled option because a well known tuner I used had promoted these injectors for there cars. and yes I know that drilling out injectors obviously will not flow as good as designed high flow injectors, but they probley would of suited me better because I am only after about 270rwkw, and peace of mind that ford dont void my warranty. As for the injectors that eugene supplied me, I have nothing against them as I have only heard good reveiws about them and they do the job when it comes to further mods 300rwkw +. The only prob I have with these injectors is that when my t goes in for warranty or service the injectors need to be pulled out and the adapters need to be cut off, aswell as hooking up the standard injectors and adapters. otherwise my car blows a sh%$ load of smoke on factory tune.
