Hey guys, i have a 94 Accord lx 5spd and i have been getting less than 20 miles to the gallon with and AEM Cai and DC headers. I also have some spark plug wires, but i dont know how old they are cause they were on there when i bought my car last march. Some people say intake and headers increase mileage, but mine decreased. ANy suggestions why i have shitty mileage.
