Javascript – Adding new element to array using for loop

I’m trying to convert url. Using for loop to extract Acura, Audi. Here what I got so far:

var newSrpParams = 'year=2020-2022&make=Acura&make=Audi&model=A3&model=A5&trim=2.0T%20Premium&trim=2.0T%20S%20line%20Premium&normalBodyStyle=Hatchback&normalBodyStyle=Sedan&odometer=13000-38000&internetPrice=20000-50000';

const newSrpParamsArray = newSrpParams.split("&");

var oldSrpParams;

var makes = [];

for(var i = 0 ; i < newSrpParamsArray.length; i++){
  if(newSrpParamsArray[i].includes('make')) {
    const make = newSrpParamsArray[i].replace('make=','')
    makes.push(make);
    console.log(makes)
  }
};

The result is

[ 'Acura' ]
[ 'Acura', 'Audi' ]

As you see it has one more array. Is there a way to get only [ 'Acura', 'Audi' ]?
