I see you like the Autolite. Whats your opinion about the Brisk Racing?

I was saying nope to the autolite being a 1 piece. but there have been nothing but complaints on brisk and champion so I stick with what works.

I bought a set of Brisk awhile back but never installed them because of all the bad comments I heard. Well my car started missing and wasn't running right so I decided to install the Brisks (gap them at .032) until I got another set of HT0s. that was about 4 months ago. After several passes at the track and spirited driving they still performing good. I removed them last week and still looked good. I cleaned them, re-gap them and installed them back.

I understand. What were the complaints? The only reason I keep asking questions is because a one piece designs seems it would be better. The stock plugs seem to be notorious for breaking apart and that is why I'm interested in a different design.

Thanks for answering my questions.

They foul quickly. Just do a search on them on a few forums.

You must be reading something into that article that I didn't see. They compared a worn out set of stock temp range plugs gapped at 0.055" to a brand new set of colder plugs gapped at 0.033" on a supercharged motor. Duh... of course it ran better with properly gapped new colder plugs. But that doesn't make the Brisk better than Autolites or anything else. In fact, I seem to recall more negative comments than positive ones from real people using Brisk plugs.

no prob

I wasn't reading into anything. If I see a magazine (with their knowledge and experience) use a certain brand it makes me think they chose that brand over the others for a reason. Could be sponsorship or quality, I don't know.

It usually means that they are paid advertisers. That's how the mags all work. "Send us money, we'll talk about your products/services."

I ran across some where on some HT2.. they are supposed to be colder then the HT0.. are these vaporware?

No, they are hotter than HT1's (stock).

HT2s are stock plugs for trucks and like Fin said they are hotter than HT1s. They are great for n/a applications though.

I'm getting more confused by this.

HT0s: normally for boosted or nitrous, but I've seen references for N/A that are mostly track driven (high RPM usage)

HT1s: good stock replacement plug for everyday use

HT2s: "great for n/a applications"

So what about a car that mostly either driven to a cruise in, or raced hard at the track? I can see pros and cons for all 3 heat ranges...

i found them cheaper than this:

I found these on ebay, but i only paid $46 for a set of eight:

Your car sounds like it is driven like mine. I will be installing the HTO's in my N/A car soon. I have allways ran a colder plug in the previous Stangs I've owned from 4valve mod motor to pushrod motors and all were N/A.

Are the Autolites a one piece?

+1 on the Brisk.

Installled a set of 3VR17YS's ($16.99 ea.) Out of the box they are gapped at 30 thousandths. Tested the resistance across the plugs, all ohmed out between 5500 and 6500 ohms. Regapped the plugs at forty thousandths and installed them. (Ford recommends between 35 and 55 thousandths for N/A cars using the Ford plug)

By the way, the plug change out was at 48k miles. All of my plugs were froze solid in the heads. Took almost 3 hours to get them out following the TSB for spark plug removal.

Just put 800 miles on the car last week, car seems to be running well.

So the HT1's arnt a one piece plug? I broke so many on the first set I dont wanna do that again.
N/A daily for the Mrs...

I like one piece plugs rather than the 2 piece design so I don't have the issue of regular or future removal. Which ones above are 1 versus 2 piece? I put in the 1 piece Champions 4 years ago after removing the OEM 2 piece plugs and have had no issues - although I should pull 1 or 2 to see what they look like. Good mileage (relatively) and no misfires so far and no worries about removal.

All plugs listed above are one-piece design, except for Autolite HT1, Motorcraft SP462, SP515, and SP546.
