Fits new gen Creta and alcazar
This fits exactly for creta, alcazar 1.5 TGDI engines so go for it good quality, not much increases in intake sounds as fitted in orginal air box. You will feel the power difference right away, sluggishness at lower RPM is much better now and pull is better too with increases in mileage. Overall value for money.

Throttle Response Boost for My Hyundai Creta 1.6 Petrol 2018
K&N 33-2451 is a perfect fit for my Hyundai Creta 1.6 Petrol SX+ Auto (2018), which originally uses the Hyundai air filter part number 28113A0100. I’ve used this filter for only a few days, under 100 km and I can already feel a some improvement. The throttle response is sharper, and the acceleration feels more immediate. It’s not a dramatic transformation since this is a naturally aspirated engine, but the refinement and responsiveness are clearly better. For anyone looking to enhance the driving feel without modifications, this filter delivers exactly what it promises.
