This was 'back to back' runs, without tuning (if I recall correctly).

I am not sure what Roy's will do, seems how his is thicker than the PHP unit.

Paul's High Performance - Spacer

PHP Intake Spacer Review by Guest M1R Reviewer Steve Foley

The Paul’s High Performance intake spacer for the Mach 1 is designed to increase runner length by increasing the distance between the intake cover and intake by means of a 3/8 inch spacer and gasket. This improves airflow, reduces restriction, and cools the incoming air charge. PHP reports gains of 4-8 RWHP/TQ with this spacer. The kit comes with an intake spacer, gasket and 5 new intake bolts.

The Mach 1 Review decided to put the spacer to the test at Apex Motorsports (www.apexmotorsports.com)in Santa Clara, CA. The Mach 1 used for this test has been modified with a K&N filter, 2 ½ in. Magnaflow high flow X pipe and 2 ½ in. Magnapack CAT Back. A baseline was obtained with these mods on Jan. 18th 2004 on the same dyno on a considerably colder day. The car also had its air box snorkel and MAF screen removed. The mileage on this car at the time was 7,000 miles. The mileage on the car at the time of the spacer test was 9,000 miles and the ambient temperature was much warmer. The air box snorkel and MAF screen was also in place at the time. The Mach 1 Review prides itself on reporting accurate and straightforward information, and that is why it has included the mileage/snorkel/screen difference on the test car.

The baseline dyno numbers were achieved with 3 pulls, and the results were a best of 285.9 RWHP and 295.6 RWTQ, both SAE corrected. The A/F ratio was a steady 12.5 throughout with a dip to 12.0 between 4,000 and 5,000 RPM’s. This RPM range also corresponds with the peak RWTQ numbers.

The spacer test numbers were achieved with 2 pulls, and the results were a best of 289.0 RWHP and 310.4 RWTQ. The A/F ratio was also a steady 12.5 for most of the pull, with a jump to 13.0 between 3,400-3,800 RPMS’s and a dip to 12.0 between 4,000-5000 RPM’s.
Overall the gains were 3.1 RWHP and 14.8 RWTQ. The RWTQ gains were highly welcomed, as the car seemed to have lost some low-end torque after the install of the high flow x and cat back.

Overall the installation takes anywhere from 30 minutes to an hour depending on mechanical aptitude and experience. The shaker must be removed and it is highly recommended that the EGR assembly be removed as well, as this enables you to completely remove the upper intake. Others have tried installing the spacer without removing the EGR and this only allows you to lift the upper intake so far, causing you to slide the spacer and gasket in place. This leaves you to guess on whether or not it is properly aligned and in place. The kit comes with 5 intake bolts that are longer than the stock bolts. 2 bolts must be re-used, one that holds the throttle linkage mount and the other that is directly across from the throttle body. Simply remove the shaker/EGR valve, unbolt all 7 bolts from the intake spacer and lift the upper intake up and off. Place the spacer on top of the existing gasket and place the new gasket on top. Re-install in reverse order and there you have it.

While the Mach 1 review doesn’t like to subscribe to “butt-o-meter” results, the PHP spacer is definitely a seat of the pants mod. The Mach 1’s 32 Valve motor wakes up at 3,500 RPM and with the PHP spacer the car seems to pull harder from that point on and more low-end torque is definitely felt through the gears. No stalling issues arose from the installation of the spacer which seems to be common among other intake modifications.

The PHP intake spacer retails for $90.00 at Paulshp.com
