Had a K&N induction kit for a Toyota Rav - which I sold to Mr Mince after my head went pop!
He fitted it at our Scarbrough Meet with no problems at all ...just need to trim one of the pipes provided in the kit to ensure the filter fits in the empty airbox space
Swanny's right about the PCD - full spec:
PCD = 114.3 x 5 stud
Offset = 35 to 42
Bore = 60.1
Have a look at this PCD Chart - HERE - to see what similar PCD fits.
Wheel Load Index is critical - for example, MR2 wheels fit but aren't strong enough and can buckle.
Often (used) Sellers don't know where to find their Load Index - usually stamped on the inside of the rim - so often it's best to check kerbweights of the vehicle they come off.
See - HERE - for Load Index Charts...about halfway down the page
17"s are a good fit for an Esti - know of some who have fitted over 18" with scuffing issues :
