Not on a civic!.. on a civic whatever you know about the laws of physics get thrown out the window, because they have v-tec yo!.. Anything and I mean ANYTHING you add to a civic gives it more horsepower even if you paint your dash that’s 0.25 horsepower right there, add racing pedals that’s like 1 whole horsepower, canadian tire airfreshner BANG!!! 0.5 horsepower especially if it’s french vanilla.
And LED valve caps are pure serious yo they work like v-tec under regular conditions they add like 2 horsepower but when they start blinking they add an extra 0.5 horsepower!
You need to catch up on your civic mods.
