Hi,

I solve it coping Price.php to Local->Mage->Catalog->Model->Layer->Filter->Price.php

then I added an if to the products biger than 10000000 (my products with out prise have a big numbers )

/**
     * Get data for build price filter items
     *
     * @return array
     */
    protected function _getItemsData() {
        if (Mage::app()->getStore()->getConfig(self::XML_PATH_RANGE_CALCULATION) == self::RANGE_CALCULATION_IMPROVED) {
            return $this->_getCalculatedItemsData();
        } elseif ($this->getInterval()) {
            return array();
        }

        $range = $this->getPriceRange();
        $dbRanges = $this->getRangeItemCounts($range);
        $data = array();

        if (!empty($dbRanges)) {
            $lastIndex = array_keys($dbRanges);
            $lastIndex = $lastIndex[count($lastIndex) – 1];

            foreach ($dbRanges as $index => $count) {
                $fromPrice = ($index == 1) ? " : (($index – 1) * $range);
                $toPrice = ($index == $lastIndex) ? " : ($index * $range);

                //EGS if toPrice is more than 20 the 20
                if ($fromPrice >= 1000000.1) {
                    $data[] = array(
                        'label' => 'Enquire',
                        'value' => $fromPrice . '-' . $toPrice,
                        'count' => $count,
                    );
                } else {
                    $data[] = array(
                        'label' => $this->_renderRangeLabel($fromPrice, $toPrice),
                        'value' => $fromPrice . '-' . $toPrice,
                        'count' => $count,
                    );
                }
            }
        }

        return $data;
    }

Hope this help someone,

saludos
