Took less than 5 mins to install, very easy and no fuss! It doesn't make that high pitch whistle sound like the other spacers on the market which is good. I feel more power mid range but not sure about gas consumption yet as its only been installed for a week. Overall its a good buy and a nice upgrade for my H3's 3.7L I5 engine.
