It depends on the tint percentage you go with. Ceramic is the same as standard in that regard. It does not let more light in compared to the same percentage of standard tint, if that's what your asking.
Yeah but the DH have different intakes too. Considering they both have similar airboxes and the the HP difference is only 14, I'm still skeptical youd be able to get 20 HP on a stock GT with just a tune. Traditionally the Ford tunes would include an intake upgrade with the tune.
Yes it's one piece per side that uses the factory screw underneath to hold it in place. See my pictures and his video above. It's very simple. Not sure what else you're asking, sorry.
Got these pretty quick from Germany and installed them today. Took about 5 mins total. I really like that it uses the factory screw to hold it on. They fit very nice and secure. And best of all no JB weld! I did it with the car on the ground so the after pictures suck.
I did some experimenting today. And yes, the fan speed does change with temperature. Put it on auto high, then toggle the temp up and down. The fan speed will change. I think the issue is people crank the temp down to the mid 60s thinking it will cool faster. But that just means the fans are...
I've long suspected the factory tune was pretty aggressive. I think a Ford tune giving A 20hp add with the factory air boxes might be a little unrealistic. Hopefully I'm wrong.
