Acceleration before and after spark plugs replacing

Nissan Altima 2009 in-line 4 with straight pipe - is there any difference?

I didn't realize this was km for a second and was like dude are you okay?

Got mine done today. I had to research my results since I was in disbelief. Thanks

changed mines after 2 whole years had the NGK’s they last a while, but I knew my car wasn’t performing like it used to, , feel like I now have my baby back ❤️😍

i just changed mine, there were multiple cylinder misfires and now it rides so smooth, and now i can floor it without the check engine light coming on

Swapping plugs isn't exactly going to increase performance, but it in this case it seems that the old plugs were worn out and torn up from normal wear and tear. Plugs can also lose performance from oil getting into the chamber from worn piston rings.

Generally called a tune-up but that's usually a term used when replacing plugs, coils, fuel filters, and air filter all together.

Low tire pressure will make a difference too

Sound alone was the difference. Ni science required for this case

Good vid. Just changed mine out today, 2010 to 2024 May 29. 162, 000 miles later

Afterwards it sounds different, it is smooth and clean.

Just replaced my spark plugs too. Old ones were really dirty I can’t even describe to y’all😂

Huge difference. I am changing mine out today.

Easy to see the difference. Good stuff.

It’s so nice to see everybody changing out plugs in the comments !

How many miles were in the ones replaced?

My car was running fine but I decided to replace the spark plugs after replacing with aftermarket autolite my car is acting wird, , , should I put back the old ones ..?

I got a C43 amg and recently changed my spark plugs and I noticed a litteral gain of 30whp on dyno after changing the spark plugs so it does make a difference the car feels insanely fast now on my tune was shocked cause the car wasn't misfiring or anything but there was lack of acceleration.

[younggeezoneplus]

Those of you looking for difference is simple...when you have fouled plugs the car won't respond to the acceleration right away ..in the second video his acceleration response was fast

[godisoncod]

These are 60kmh pulls tho, what about 0-60mph ?

[ozhoneybadger]

My is250 plugs ain't been changed for 4 years but only done 30k miles. Meant to be 60k replacement shall I change em let me know someone please

[miguellara]

I changed the plugs in My mustang feels like acceleration got better it accelerates faster tha before
