I dont know if you folks have seen these yet but they look like a good way to save money and improve gas mileage and go green. A air paper air filter for my suburban runs about $25 and it you need to change it about every third oil change - 10k miles, of if you drive on dirt roads or dusty conditions sooner. So I spend about $75 a year on filters multiply that by the life of the truck and that's alot of money! K&N makes a filter that is serviceable so you can just clean it out and recharge it and keep on trucking cost is around $65-75. Still saves money in the long run though. Well Spectre has came out with their Spectre HPR line of air filters it uses similar or the same method that other brands do but the cost its ALOT less! http://www.spectreperformance.com/#HOME Spectre Performance Air Filters: use high-quality washable/reusable cotton gauze; provide superior filtration; improve fuel economy; increase horsepower; and do not void manufacturer warranties. The one for my truck its $29 and you can see it below. That is almost the same price as a throw away paper one but this one has a lifetime warranty! Well I was pretty much sold right there I mean it saves money, increases horsepower, is better for the environment and did I say it saves money! Well it doesnt stop there Spectre is offering a $10 rebate on these filters so now my new filter is down to less than $20!!! Cant beat that deal and if you don't like it what the heck you are still out less than the cost of one paper filter. The filter has to be ordered they aren't in stock at the stores yet but you can get them online from like jegs and Summit or locally from Advance Auto , Autozone, O'Reillys and if they say they don't have them ask them to look up air filters for your ride and it will come up. The inventory software has been updated apparently but the stores don't all know about the filters yet. My filter will be here around the 27'th and I will get some more pic for you all when it comes in and then do a MPG test to see if there is any difference.
