Why do soo many people hate on the hks mushroom intake? I understand in hot temps it ain't gonna be good but here in uk we rarely get hot summers and if at most 2 months of summer.
I also hardly drive the car it's a weekend toy have put 1k miles on in 1 year. I get that the mushroom filter can disintegrate but surely if you change it every year it shouldn't?
But Yh il look to see if it drops any further /gets worse, then start looking at replacing thermostat
