wow can't believe how pricey this is ,
i made a switch operated sprayer for free/ 20 bux
denso washer bottle pump off a el ford at the wreckers , spray nozzle(s) off various bonnets at the wrecker , 1L spring water bottle with the top drilled to suit
and done
couldn't see any difference of intake temps at cruising speeds it should help after a long thrash or on a hot day
