It just plugs into the OBDII. I used one for 15 months before I got my tune. Just make sure you remove it before emissions testing to give the readiness monitors time to reset.

I found the Range Technology brand for $210. Found a "Fits Range Technology" RA003 brand for $80. Then I found some other ones that ship from China for $58, also stating that they are Range Technology RA003, but these look very Plain-Jane black with none of the aesthetic decorations that are on the $208 version.

Also, I'm scratching my head here regarding compatibility, on some sites that sell the Range RA003 AFM delete they say that it is only compatible with the Silverado 1500. I don't want to buy the incorrect one. I thought RA003 was the model number.

Go down the page and select the filters for your car. RA003 is correct. I would only purchase it from Range or Summit Racing if it were me. I spent about $200 on mine from Summit Racing
