I just recently added nitrous to my truck ( 75 shot ). That same day i also changed my spark plugs. This was about a month ago. My question is after how many oil changes do you think i should change those spark plugs to avoid the you know what.

I also dont use the nitrous much.

Wat do you think?

 

What the HELL possessed you to spray that motor? Lol, if i were you I'd change them twice as often as stock...but that's just me.

 

Check them every 10,000 miles. Change them out when they start losing their gapping.
How's that N20 working for you?

 

whatd you spend on the nitrous kit and what is it to fill the bottle?

 

Thats what i was thinking maybe evey 3 oil changes just change them and thats it. With the nitrous it just jumps off the line as long as you can get some traction ( definetly a problem with stock tires ) and when its rolling the miles per hour fly. Moves good for a truck lol. I spent $425 on the kit installed and everything the bottle fill is $28. But im in miami, fl. Im sure it varies by place.

Im thinking of going with the 4.10 gears but im worried about mpg i do about 25 miles a day on the highway. I have the stock 3.55 ls now.

Do you think that 4.10 will kill to much mpg?

 

You'll get good at changing them!
I have 4.10s and the highest mpg I've seen is 18, If I get above 14 I'm super happy. City mileage is around 10....

 

When your doing about 65-70 where are your rpms at with the 4.10's

 

It's 2000 at 60, I can check 70 tonight

 

Thanks man i'll apreciate that. The reason i ask is cuz thats what i normaly cruise to work at.

How much do you think ill be looking to spend on the gears and labor all together?

 

Ok, so it was 2300rpm at 70 and 2150ish at 65.
