Can anyone tell me if there is a HP gain with the install of a cup air box? If so is the install hard or just a simple bolt in?:shrug:
Might take an extra 15-30 min, but it was pretty easy.No hp gain that I know of, but it does increase the surface area of the air filter, and changes the sound somewhat (most people like the difference, I didn't).
You really need a friend to help with the install, as it's not as easy as some make it out to be.
I would say it's a worthwhile mod for nothing else than the low price/additional filter surface area.
You must have put the TRD sticker on the bumper of your Lotus. It"s not a HP gain, It's the Lotus trying to get it off!!rotfl:nanner:I have a cup box and TRD reusable filter. I didn't gain any HP from this combo, but the TRD sticker gave me about 3 extra HP.
