Look at the pictures they have, the fuel rail hold downs are inside then outside of the fuel rail. These fuel rails will not work what so ever. I’ve tried new orings and modifying the hold down brackets. I cannot get them to seal. If you need a good insurance claim due to a car fire buy this kit.

I bought two of these accidentally but it gave me an opportunity to see if both had good quality control, I have to say both were totally level, clean, and flat against heads in all 4 corners without gaskets.I bought intake and rails with no throttle (I have a 92dbw) it is clean with no imperfections rails had zero burr’s in them and fittings all went on without leaking, comes with crossover I didn’t use and I was totally blown away both are flat and don’t have a scratch or ding, these new intakes are much thicker when you knock on it it sounds like a quality intercooler end tank very dense, I will be dyno testing one on a twin turbo car and we’ll see how it acts, with people wanting 300+ for stock intakes this very well might be the best solution.The only con I had was fuel rail hold downs pushed my injector and hat combination towards valve covers but they’re just stamped steel and I was easily able to bend them to appropriate angle. I’ll deal with that as it might be my fault with spacers or just plain for the price I will lean on it to fix it, anyway looking forward to updating after dyno and what I think.

The flange does not have relief cuts in it for the head bolts, causing the flange to not sit flush with the heads creating a massive vacuum leak. Other than that the hardware want the greatest but everything lined up correctly

Nothing lined up i thought I’d be a good product but it’s not . Do not buy .
