w00t,install-age

 

anyone expirement with the ACDelco "rapidfire" plugs? Back on the j-body.org i talked with nelson from RSM Racing (now "Z-Spec") and his suggestion for boosted application was the Delco Rapidfire. I forget if it was #3 #4 #5 or #8, but one of those he swore by. Had a buddy do a garrett t3/04e on a 2.4 Quad motor, and another do the RSM Racing stage 3 vortech blower on his 2.4 quad motor, both used those rapidfire plugs and bought them by the case (just because fine tuning fuel issues too rich or too lean, you will foul out MANY spark plugs... regardless of what brand you use...)

anywho, yeah... what do you all think?

 

You sound like you should run your own DIY show or something lol. Good vid and I love the part where the plugs ARE NOT A ****** MOD.

 

that part was great, you should see his other vids, funny as hell

 

Yup i bought them today, and am very impressed! Cloudio your the man!

 

I went to Autozone today to try out the Platinum 4's. They didn't have any. The guy said they were recalled for pre-mature fouling. Anyone else here this ?

 

someone made a post about this a few pages ago,oh ****! it was about them snapping

 

Think im going to hold off on installing mine for a few days and see what is found out about this...

 

I was going to stop at Autozone today and pick some up. After seeing that comment, I'm glad for now I didn't make it. Otherwise they would be in the car right now. And if there is problems with them, I would prefer to hold off till we hear more.

 

I completely understand your guys reason for waiting although there are already over 5+ ppl on here who have installed these and have had nothing but great things to say about them
ive had mine in for almost a month now and they still run as good as day 1 iam trul impressed.

and at any rate i find it hard to believe that there is a recall at all because if there was
WHERE THE HELL IS ALL THE INFO on it !!!!!!! I havent even seen 1 sentence from a reliable source dictating that these plugs are no good

so moral to the story the only thing that speaks louder then words is actions .....
Me and tons others on here can vouch for these plugs there spectacular ....\now stop drowning your hearts desire and pop these ******* in ......: )

 

You actually believed that someone from AUTOZONE knew what the hell they were talking about?

 

LOL . Yea, you crack me up

 

That's why I'm checking here first ! Before I spent 30 bucks.

 

Ok, guys... you know I had to get a set and see for myself.

I definately noticed an increase in low-end torque off idle and up to about 1/3 throttle.

This improves the car's "driveability" for lack of a better word.

Since this is how people drive most of the time, there should be an increase in fuel mileage.

I did not notice any increase in smoothness (my car runs super smooth after my header install anyway). Also, I don't feel any increase in power topside, but what do you expect for $30?

Overall, I agree, it's money well spent.

BTW, there is no recall. That is total BS.

 

so THE spark plugs to buy are the Bosh platinum 4s?

 

Roffle.

 

Got any pics of the big bore throttle body you have? What was the price for this? Did you notice any gains?

 

I thought the sms doesnt work for us

 

Yes, they work, but it's only about 2mm bigger than stock.

They are only good for maybe 2-3hp for $150.

Whether it's worth it depends on how bad you want to win.

When they come out with one 8-10mm bigger, I'll get one.

 

this what i heard too, I want a bigger one and no vendor has stepped up to the plate yet

 

I noticed a bit of a difference in low end torque....... i already had a CAI on it and Catback exhaust at the time so when i had the TB put on, i could tell a minor difference.... its one of those building block parts ya know........ itll help more with other stuff

 

Yea, yea, I quoted myself. I went to the third auto parts store and they didn't have the platinum 4's either. This guy said the Plat 4's were being relaced by the Fusion plugs. He didn't know why. The Fusion's were 10 bucks each. I'll wait and see what's going on.

 

thanks for the update,now I'm curious about these fusion plugs

 

Ok, so which is better to go with? The +2 or the +4's? I don't want my **** to melt. lol. Also, one of you said you run 91, will this "un-mod" work better with the higher octane gas? I always run 93. Lastly, I've only ever done this once before, on my 138,000 mile 93 Accord when I had it. How often do these need changed? Not very, right? Do aftermarket ones need changed sooner? Thanks!
