i've done a lot of reading here, but not much posting. i've got a 94 Accord with 217k on the clock. i've only had it for ~11k and i've used Cam2 SuperPro 10w-40 with a Purolator PureOne filter each change. i recently put 3 bottles of Lucas fuel conditioner through using it every other fillup. it seems a little smoother on cold start and the throttle response is noticeably better. so being that some cleaning on the fuel side showed signs of improvement, i thought a cleaning on the air side might be in order. i'm looking at SeaFoam, Mopar Combustion Chamber Cleaner & Amsoil Power Foam (APF). i figure any of the 3 would be suitable for this application but i thought i'd ask to see if anybody has used these products and noticed better results with any particular brand. thanks.
