Sorry for the corny title, but i just changed my spark plugs and it seem's that my car has a slower response then usual. It feel's smoother and less jerky when i shift in SS mode, but the pick up in low rpms is not working. I used to pick up alot quicker in low rpms before i change my spark plugs. i had oem honda spark plugs, then i changed to the 4 prong borsh platnuim. Should i had gotten NGKs?? but is this normal i never change the spark plugs before. thank you for your time.

 

Bosch are for BMWs.... that's what i use in mine, but....

NGKs are for Hondas, get rid of those 4 prong Bosch plugs, and get te $16 ea. NGK platiunums specifically for the Prelude, you'll be much happier

 

I am using the bosch plus 4's as well, no problems, are you sure they didn't give you the si plugs when you have a vtec or something like that

 

NGK Copper plugs for the H23a1 motor, no reason to need anything else...

 

i tried Bosch and the sucked compared to the NGK's, so i just switched back

 

you sure that the oem fuel injected spark plugs werent used before? that can really kill your motor if you switched out for normal ones.

Yep, you dont need anything else..Unless you like paying 50 bucks for a set of platinum plugs, that you dont need.

 

get densos... mmm denso, there nice and all but i dont think they are worth the 62 bux my ex paid for them... but it wasnt my $ so whatever. but they will probably out perform whatever else is out there
