For all: (optional)
I am reminding everyone that did the mod to keep there charcoal filter or fish tank filter before having your next smog test and reset your ecu days before the test. And also replacing the stock air filter with a performace filter (ex. K&N, AFE etc.) to not to over oiled the element for MAF sensor failure might or will occure. That is why I myself will get an AEM drop-in air filter. Again, guaranteed results for everyone will totally not to be the same for driving behavior and driving conditions, but should notice a diffrence. Enjoy while we can.
